All clear!

A cease-fire agreement has been obtained (I'm not sure that there's an actual written agreement) between Israel and Iran, so we have stepped down from full scale alert after the "12 day war". I opened the bomb-proof windows of our bedroom and returned to the dining room the various chairs that I had moved into the bedroom. We had a full night's sleep without any fear of being woken at some hour with a warning emitted from our phones. All services are back to normal.

After getting up and walking the dog, I did a little work then walked to the swimming pool that opened for the first time in two weeks for 'swimming for health' at 7 am. The water was not cold, making it easier for the body to swim. As this was at the beginning of a working day, I didn't want to swim too much - only 8 lengths without stopping - so that I wouldn't be tired during the day. I could make a habit of this.

This swim was also before eating, so hopefully I burnt off some visceral fat1.

Otroverts and more memories of Habonim camps

I started reading a book yesterday about otroverts - not introverts nor extraverts - and whilst I wouldn't categorise myself as such, I started wondering how and when I changed from a generally happy and gregarious person into a generally unhappy and introverted person. I thought that there might have been a clue in my various blogs about Habonim; there wasn't, but reading between the lines here and there did give me a hint.

Until I left school in 1973, whilst I might have kept my Bristol and Habonim lives separate, I was fairly integrated with the other boys at school. Apart from our studies, we had sports along with progressive rock and/or folk music in common, and externally at least I was the same as the others. Then came the year 1973-41 in Israel, during a war, with people who were supposedly similar to me but often as different as chalk and cheese, and often a few years older. If that were not enough, I then spent the next four years as a schizophrenic: during the days, I would be with people with whom I had very little (if anything) in common, either at university2 or during the two work periods, whereas in the evenings and weekends I would be with my movement friends. Then I emigrated and discovered that life on a kibbutz was not the idyll that I expected.

Reading through those blogs about Habonim, I had two more memories that I hadn't written about previously. First, cooking3: for reasons of kashrut, we didn't have meat at camp. For breakfast, all I remember is corn flakes, bread with jam, and tea. For lunch and supper, we rotated through a meal based on eggs, one on cheese and one on fish. The egg meal was probably some type of flan and the cheese was probably cauliflower cheese, but I don't remember what kind of fish dishes we made. In the summer, everything was cooked over gas rings, so there weren't that many options. On Friday nights, the leaders would serve us salami on paper plates as a treat, although I don't think that I liked this very much. Paper plates also meant that there wasn't much cleaning up to do.

At the camp in 19714, after a few days in bivouac tents, we reverted to a more familiar format. In the next day or two, I 'got off' (as the ugly expression has it) with a girl, at a speed that somewhat surprises me now (that was when I was gregarious). A day or two later, because it had been raining, we were playing games in the big marquee where we used to eat and have evening activities together when we weren't outside. I remember I was running around the marquee then something happened although exactly what I don't remember: either I slipped, or I ran into the tent pole in the middle of the marquee or maybe something else, but suddenly I was stunned and fell to the floor, as if someone had given me a huge punch to the stomach. I was helped to the medical tent, where I was examined with no real diagnosis ('stomach cramp') and left to rest on the camp bed there. Later on, friends came to vist, including the girl. The next day I stayed in the medical tent and slept another night there - I had no desire at the moment to rejoin the hurly burly. But after that, it was hinted that it was time to get up, and so I did, rejoining my friends in our tent. 

This was the year that the hormone levels were running high. Although girls weren't supposed to be in our tents, I remember one night when the boy on my left had a girl with him for some slap and tickle, as did the boy on my right (they didn't stay the night). A few days later we went on our five day hike; when my group came back, it must have been before the others as the camp site was fairly empty. So some of us - boys and girls - piled into one tent to sleep. Traditionally, we took down most of the tents on the penultimate day; we were told that we could sleep where we liked for the final night, so instead of sleeping in the marquee, my girl and I lay down outside the marquee. All we did was kiss (and at length; our lips seemed to be stuck together and I wondered how I would breathe) and I fondled her breasts. Nothing else. It never occurred to either her or me that maybe I too should be fondled.

We met up again a few weeks after the camp when I was touring southern Britain (again, the 1971 blog), but she broke up with me by mail a few weeks later. I commiserated with Sandy Denny's 'North Star Grassman'.

Time-restricted eating

Another week has gone by and another 100g has dropped off my weight. This could be considered to be 'statistical error', especially when drinking a glass of water adds 200g to one's weight. I try to keep the conditions constant when I weigh myself: Friday morning, naked, after pills (a minimum of water) and urinating as much as possible. My weight is definitely decreasing, a little bit each week, and this seems to be the way to lose weight - not by reducing the intake of calories and forcing the body to change its metabolic strategy, but by restricting the hours during which I eat, or more accurately, increasing the time during which I am not eating.

The war is helping obliquely: I am going to bed slightly earlier than usual, in part because almost every night there has been a missile warning. I am sleeping later, both because of the disturbances caused by the warnings but also because my company has not been working all week. Gradually the number of people connecting to our server and the hours that I work have been growing each day; I understand that Sunday will be back to work as usual. As a result of the sleep, my blood pressure has been lower both in the mornings and in the evenings (when I remember to measure it).

My last set of blood tests were done at the end of March; I wanted to wait another three months before repeating the glucose, cholesterol and HA1C tests, but I'll wait another month. I am hoping that the time-restricted eating along with the probiotics will have reduced some metabolic markers as well as my weight.

Israel is at war with Iran

To quote Joan Didion in her essay, "On keeping a notebook" - Remember what it was to be me: that is always the point. So I'm not going into the whys and wheres of this latest event but instead I'm going to remember what is was to be me.

We were woken at 3 am on Friday morning, 13 June: at first, we thought that it was a Houthi missile, but no, it was the home guard telling us that a state of emergency had been declared after Israeli aircraft had attacked various sites in Iran (over 2000 km away!). Friday morning was passed almost in a state of shock; essential services were open but the swimming pool was not. If by the evening we had thought that life had returned to normal, then we were wrong. At about 7:30 pm there was a Houthi missile then twice during the night there were Iranian missiles. Saturday was like Friday and Sunday like Saturday.

At the moment, life is like a hybrid of the early Covid days and the days following October 7: everywhere is quiet, people are mainly at home and only essential services are open (e.g. the supermarkets are open but the train station and post office are not). Of course, I'm fortunate that I live on a kibbutz, not particularly close to any conurbation (I wouldn't define Bet Shemesh as such) and so the possibility of a missile coming anywhere near us is extremely low.

My wife and I have a great advantage over many others on the kibbutz: our bedroom is our security room, so air raid alarms at 11:30 pm or 4 am don't cause us any bother as we are already in the security room. Even the dog recognises the alarms now: during the afternoon of the harvest festival (but before it began), the dog and I were walking outside when the alarms went off. She tugged me all the way home. Now when we have an alarm, she knows to come into the bedroom with us, something that we don't normally allow. One evening, neighbours came to share the room so I had to take the dog to another room (otherwise she would have barked constantly); she was miffed that she wasn't in the security room.

Brian Wilson RIP

What can I say about the man who in a few songs epitomised the sunny side of the sixties, more than the Beatles, or at least, complementing them? The Guardian summed up twelve of his best songs; I would agree with all but three, but that's only because I don't know those three, later, songs.

The history is here.

My first extant memory of Brian Wilson/Beach Boys was at Habonim winter camp at the end of 1966, when I heard "God only knows", although to coin a phrase, God only knows how I heard it: presumably someone had a transistor radio.

Cut to the summer of 1967: my family was gifted a greatest hits collection of the BB. I imagine that most of my favourites came from this record. Some time when I lived in London, I heard a few more interesting songs - "Darling" and "Breakaway" (that transmuted into "Takeaway", about our habit of eating food from various restaurants, but as one knows, takeaway is ... without any extra VAT to pay).

In around 1970-1, I bought a book called "Awopbopaloobop Alopbamboom" by Nik Cohn that introduced me to a great deal of what I would call 'earlier' music about which I didn't know. There was a chapter about the Beach Boys that taught me their history until then. Of course, they continued in various configurations for at least another ten years, but they didn't succeed in creating any lasting music; certainly they didn't impinge on my life.

Much much later I became interested in the harmonic structure of "God only knows" - there are several excellent YouTube videos about this song but I first read some internet article. From there, I listened to "Pet Sounds", some of which I liked very much and some not so much. [Late news: David Bennett has just uploaded his take on this song; it's worth watching for those who are interested in such things.]

I can't say that BW has had a direct influence on my life, and like most musicians, his most fecund period was when he was in his twenties, before he became one of the first famous acid casualties. So his passing is something that I note, but do not grieve about.

Diet, drugs and dopamine

When I'm not reading spy novels or police procedurals or cozy murder stories or hitherto unknown details about World War 2 or musician biographies or even straight novels (normally romance, but not necessarily), I read popular science books, primarily about the body: how it functions, how we can improve its performance, how we can lose weight, and so on. Fortunately, most of these books don't give contrary advice (although there was a book that I read a few years ago that recommended coconut oil) but rather shine a light on different topics. Thus Dr Steven Gundry1 can write about the microbiome, Dr Peter Attia can write about exercise and former FDA Commissioner Dr. David A. Kessler can write about obesity and GLP-1 weight loss drugs without stepping on each other's toes.

One topic on which they agree is that an effective strategy to lose weight is by changing when one eats, aka intermittent fasting. [A] potential benefit of intermittent fasting is improved metabolic flexibility. During fasting, the body transitions from relying primarily on glucose for energy to increasing fat oxidation, effectively utilizing stored fat. According to Dr. Courtney Peterson, a professor at the University of Alabama at Birmingham, this metabolic shift typically takes place after around fourteen to twenty-four hours of fasting, at which point a noticeable rise in fatty acid oxidation begins. The longer the fasting period, the more efficiently the body can mobilize fat reserves for energy. (Kessler, chapter 17).

For the past month, during weekdays, I've been eating my meagre evening meal at 4:30 pm in order to leave a fourteen hour window before the next day's breakfast at 6:30 am. This is problematic on Friday nights as I eat a full meal normally between 7-7:30pm, so a fourteen hour window would mean eating breakfast after 9 am. Why not? It occurred to me on Friday that on Saturday morning I could walk the dog, walk to the swimming pool, walk home and only then at 9:30 am eat breakfast. This way I get in a fair amount of exercise while hopefully the body is burning fat in order to provide the required energy - and I require a lot of energy when swimming. Instead of utilising the glucose developed from breakfast, hopefully my body is using fat. 

The result? On Friday morning I weighed 'only' 85.2 kg; this in itself is a slow but constant lowering of weight that might well be because of the probiotic Lactobacillus Gasseri. This morning I still weighed 85.2 kg, so if my eating breakfast after swimming caused any change, it was only on the micro level of visceral vs adipose fats and not on the macro level of gross weight.

Minor quibbles about the Kessler book: despite being American and writing primarily about American ultraprocessed foods (although there is a mention of Israeli research into the Mediterranean diet) - like all of these books - it starts off confusingly with the sentence Almost one in three Australians struggle with obesity and its related health conditions, including high blood pressure, heart disease and diabetes. Where did the Australians come from? Another peeve is the mixing of weight units: To easily calculate daily protein intake, aim for grams of protein to be at least 75% of your body weight in pounds. For example, if you weigh 160 pounds, consume at least 120 grams of protein per day [Emphases mine] (Kessler, chapter 18). I have no idea what my weight is in pounds, but if I dive deep into my memory, I recall that 1 kg is 2.2 pounds, so my American weight is 187 pounds and I should be eating 140 grams of protein per day. It took some time to check, but it seems that I'm eating sufficient protein, about 145 g each day (that's if I eat 200 g quinoa each day, which I don't).

My first reserve army duty

A chance remark on television last night reminded me that my first reserve army duty was 43 years ago - June 1982, when I was 26 years old and released one year from the regular army. Although the intention was that I would serve reserve duty in the laboratory where I spent most of my regular service, the various paperwork and deals had not been completed. Thus my first reserve duty would be spent in the 'daughter' base, as a medical technician. This meant packing medical rucksacks: there was a rucksack for doctors and company medics and another rucksack for regular medics. For each type of rucksack, there was a list of items (drugs, bandages, syringes, etc) and what would go into each pouch. The soldiers were split into teams of four or five, where each team had a bay with all the items sorted. Each soldier would be reponsible for packing some number of items into each rucksack.

The first day of the service was probably a Tuesday, and we spent a few days desultorily preparing rucksacks and ensuring that each bay (or as I would call it now, each kanban) had sufficient stocks. As the base had no sleeping facilities, we would go home at around 5 pm each day and return the next day by 8 am. Soon the first weekend was upon us, and a certain number of soldiers had to stay and guard; I don't remember if there were also guards from my regular unit - I certainly guarded that base many times. 

Of course, I was one of the soldiers who was 'picked' to stay the weekend; I don't recall now if we had sleeping and eating arrangements on that base. Anyway, I was doing the 6-10 am morning shift on the base's gate - this was always my favourite shift as I was a morning person and the world was quiet and cool. I was sitting in the small guard hut, almost certainly reading a book and possibly drinking tea, when cars started arriving between 7 - 8 am. I don't remember now whether there was a gate or similar that I had to open, but regardless, I was extremely surprised to see these cars, especially as they contained several career petty officers who were religious; there must be a very important reason for them to travel on a Shabbat. The date was 6 June 1982.

Soon the situation became clear: there had been an assasination attempt on the Israeli ambassador to Britain, Shlomo Argov, and in retaliation, Israel began what was originally called the 'Peace for the Galil operation' (מבצע שלום הגליל), then later became the Lebanese war and eventually the first Lebanese war. As a result, our work in the supply base suddenly became extremely important.

I don't remember what happened for the rest of day - whether I was still guarding, whether I was off duty or whether whoever was on the base started preparing more rucksacks. I don't remember if I even went home that Saturday night - quite probably not. I do remember that somewhere banks of telephones had been set up so that we could phone home to give updates.

From that day on, we worked from 8 am to 8 pm. One evening I was returning home (problematic at the time) and probably dozing in the bus, when the lady sitting next to me gave me a peach: her contribution to the war effort. The base still had to be guarded at night, and I remember that my number came up again on Thursday evening.

On Friday morning, the thorny question of who would stay the night to guard the base and who would go home (only to return the following morning) arose. As I had no way of getting home on a Friday evening nor returning the following morning, I volunteered even though I had stayed the previous night. I have a memory of sleeping in my 'sheet sleeping bag' on a grass verge although I don't recall from which night this was. 

As a reward for my volunteering, I was sent home at about 4 pm on the Saturday afternoon, and managed to hitchhike home for a much needed shower and rest. More importantly, I was never called upon again to spend another night on the base. I don't recall what happened the next Saturday; probably I came in late. I do remember that one of our team was religious: he reported in on Saturday but sat on the side and read a prayerbook in lieu of packing rucksacks.

After two weeks of intensive work, the pace was reduced somewhat, and each team was allowed to release one member each day for a day off. This was already two and a half weeks into our four weeks' service, so the end came quite quickly. The reserve soldiers that we had replaced at the beginning of June came back to serve another few weeks on the first Sunday, so they effectively served nearly 60 continuous days. 

That was the extent of my service in that war that brought a very troubled six months to Israel. The nadir of this period was the Sabra and Shatila massacre, which although was not purpetrated by Israel was at least allowed to happen. All through this period, defence minister Ariel Sharon basically lied to the Prime Minister, Menachem Begin, about the scope of the operation that became a war. A year later, Begin would resign - I may not have agreed with his policies but at least he was a decent human being and knew how to accept responsibility, unlike his successors who are driving Israel further and further into the mud with every passing day.

The 2025 swimming season begins

As usual, the swimming pool opened at the time of the Harvest festival (known as Whitsun to our Christian friends), but the hour designated for 'health swimming' was either at 10 am or 11 am - too hot to walk to the swimming pool, which is on the other side of the kibbutz from me. So it was only this morning that I made my debut performance.

As per previous years, my left forearm starting hurting after a few lengths. Presumably that pain will go after a few swimming sessions as the muscles rebuild. The water was c-o-l-d, as expected, but instead of going in slowly, I walked in quite quickly; the cold is still a shock to the body (and some might say that it's beneficial), but this way I had one short shock instead of an elongated one.

I swam 4 X 4 X 4, which is enough for the first time. I'll see how things go tomorrow, whether I'm swim more or rest less.

The hot shower afterwards was very pleasing.

Problems on the pedalboard

At our last but one rehearsal, we were about to play a song in the key of Bb. For this song, I 'cheat' by setting the octave pedal 1to transpose up by 3 semitones then playing in G. When I pressed on the pedal's footswitch - nothing happened except a sort of delay and a crackling sound. With no time to waste, I took my capo (which was sitting in the guitar bag as I don't normally use it), placed it on the third fret and proceeded to play as usual. Another song is in the key Cm, so again I capo up three frets and play in Am.

I thought that the problem might be some form of interaction with the new pedal2, so yesterday I changed the order of the pedals, placing the octave pedal first (after the tuner). This made absolutely no difference. What is galling is that the pedal can transpose down; I ended up using this functionality in order to play a song that is notated in Am, but the singers want to sing it in Gm. Thus I set the pedal to transpose down two semitones - this was OK. I suppose that for the song in Bb, I could set the pedal to transpose down four semitones and play in D, but for this I'll have to learn to play the song in D (a minor problem).

As I bought the pedal at least 15 months ago, I assume that it's no longer under guarantee, so I don't have many options other than buying another octave pedal. The Donner pedal cost $45, if I remember correctly, but maybe I can find a pedal from another manufacturer.

I used the new multifunctional pedal in quite a few songs yesterday; I notice that I'm using the Leslie and tremolo pedals less and less.

Another bluetooth headset

I was a bit too hasty when I wrote1 about and praised bluetooth headphones a few weeks ago. All the people with whom I spoke that day said that the quality of my voice was such that it sounded as if I was underwater. In other words, those headphones might be good for listening to music (and as it occurred to me a bit later, they're functionally the same as the pair that I wear when I'm walking) but not good for talking.

And so I looked for a better solution, that seems to be the YYK-520 headset (I didn't order from Amazon although the link is to there). I can listen to music via my normal headphones, and when someone calls, I can remove those headphones and clip on the headset. Speech quality seems to be fine.

The headset comes packed in a case that can actually serve as a charging cradle. Inside the case there are also two replacement earpiece covers, although apparently these are of different sizes (surely what is important is the earpiece itself, not the cover). The charging cradle comes in a box; somewhat hidden is the 'user manual' (quite detailed but very small) and a cable suitable for charging.

My wife telephoned me a minute ago whilst I was in the middle of writing this blog, so I had a chance to test how quickly I can put on the headset and what the sound quality is like. The sound was a bit tinny and quiet; I hope that I pressed on the correct button to make the sound louder, but I've probably made it quieter. No doubt it will take me a little time to get used to this device. The key seems to be to insert the earbud first then arrange the ear clip.

There is another option that is compatible with wearing music headphones most of the time (that will still have to be removed when there is a call): a rechargeable wireless business clip-on earbud, as pictured on the left. The device can be clipped onto my shirt and kept there all the time. Whenever someone calls, I can whip off my music headphones, insert the device's earbud into my ear and start talking. As far as I can figure out, the device contains a microphone. The 'manual' appears to be a joke but it shouldn't be too difficult to figure out how to work it. This would cost me a third of the price of the YYK-520, so it's not much to lose if it doesn't work out. The low price also reflects the quality of the device; it's probably fine, but I can see that a great deal of attention was paid to the YYK-520 (eg the charging cradle). I saw someone with this kind of device in the supermarket last week.

Now I can emulate Lt Uhura (showing my age) who predicted the bluetooth earset at least 50 years before they became a reality.

A cheap source of Erythritol

I haven't written much about erythritol over the past two years, but every day I drink some in my breakfast herbal tea. Sometimes I use it with black tea and milk ("English tea"), but the result has a slightly unusual taste that although drinkable is unsatisfying.

So every few months, I have to buy more erythritol. Usually I buy from some Internet merchant in Israel, but these seem to change each time as either I can't remember from whom I ordered the previous, or they don't have any in stock/have stopped sellingwhen I go to order. This time I found a new supplier, "Nifla'ot hakoleh" who are selling erythritol for 19 NIS/kilo. This is 'bulk' erythritol, not prepackaged, so one can order any weight that one wants (within reason). Of course, an Internet merchant has to add delivery costs, in this case a rather steep 39 NIS (normally shipping is about 25 NIS, if I'm charged at all), and so 3 kg cost me 96 NIS, or 32 NIS/kilo. The sugar came in three bags that I did not weigh.

At what price is the health foods shop in Bet Shemesh selling erythritol? They offer several packages: 400 g @ 19.9 = 49.75 NIS/kilo; 260 g @ 26.9 = 103.46 NIS/kilo; 500 g @ 33.9 = 67.80 NIS/kilo. So why bother going there, when they are at least 55% more expensive, not including the cost of getting to the shop?

I can't find the payment for the last batch of erythritol so I can't compare, but I'm sure it was more expensive.
