The week that wouldn't end
Over the past several months, as events came up I bought tickets to things I was interested in, so it was completely coincidental that I ended up with three events in London this week. (And nothing for two weeks before and after.) That would have been fine, of course, except that all four of my projects -- that have been running me ragged over the past month -- suddenly needed me to be travelling this week!!
Tuesday I had to be in Sheffield, Wednesday in Coventry, Thursday in Manchester, and Friday in Exeter! All of these were 2-3 hours from my home. Again, that would have been fine -- I would have just stayed in hotels -- except that now I needed to travel back to London each night to attend these events!
I did catch two breaks -- the trip to Coventry was changed to a trip to London, and I was able to stay at my friend's hotel Wednesday night. However, on Monday -- the one day I was allowed to work from home -- I got a call at 10am asking me to be in London for a meeting at noon!
The worst day was Tuesday, when I had to leave before 6am, and got home after 10pm. The meeting in Sheffield was scheduled to last 3 hours, but it ended up lasting 8 hours, and we didn't even break for lunch!!
Friday I would have happily spent the night in Exeter and explored the British coast during the glorious sunshine we've been experiencing, but even that was thwarted--I had been tasked with security detail for my local synagogue!
So my goal is to simply survive this week, and rest next week -- I have absolutely nothing planned, and no travel scheduled! I suspect by this time next week, I'll be complaining about how bored I am. :-)

Energy
So, having dispatched the myths around protein and energy, the question remains: Where does the body get its energy from?
The answer is the "Kreb's cycle" (or Citric Acid cycle) which I will simplify at a great loss of accuracy:
Each of your cells has several hundred to over two thousand mitochondria* inside of them, depending on their need for energy. For instance, heart cells and muscle cells may be up to 40% mitochondria. All together, your body has over one quadrillion mitochondria that are constantly producing energy. Approximately 90% of the oxygen you breathe will be used by your mitochondria.
Your body takes the sugar or fat molecule and breaks it down to smaller units of two carbons. Mitochondria then use oxygen to break down the carbon and strip off two electrons, creating carbon dioxide as a waste product. The electrons, in a series of chemical reactions, are attached to a phosphate molecule, which is then attached to another molecule, changing adenosine diphosphate (ADP) to adenosine triphosphate (ATP). When your muscles need energy, this high-energy phosphate is stripped off the ATP, and it becomes ADP again. These chemical reactions require vitamins B1, B2, B3, B5, and B6; vitamin E, Coenzyme Q10; iron, sulfur and other micronutrients.
Of course, your body gets the sugar or fat from your digestive system but, unlike protein -- which is discarded if not used -- your body will happily store excess for later.
Of course, it's pretty complicated because it was designed by a blind watchmaker, but it is also very efficient, and all animals use the same basic process to create energy.
However, stripping electrons is dangerous business, because at the cellular level they can do significant damage if not controlled. Oxygen is already pretty volatile (and the reason your body uses it to produce energy), but if it picks up an extra electron it becomes a "free radical" which can rip through cell membranes, There is some fairly compelling evidence to indicate that the entire "aging process" is actually the result of the damage of free radicals over time. Experiments with aging rats, for instance, indicate that the mitochondria become less efficient and the cells themselves become "leaky" and less able to control the processes of what goes in or out of the cell.
Some interesting experiments were done with these aging rats to give them supplements of acetyl-L-carnitine to increase the mitochondria rate, and alpha-lipoic acid to reduce the number of free radicals, and found that within two weeks the old rats were as active as young rats. Of course, humans aren't rats, as we discussed on the issue of protein! (I've been taking alpha-lipoic acid since I read that over 10 years ago, and I seem to have aged just fine...)
* Not to be confused with "midi-chlorians," which is the source of the Force. George Lucas is an idiot.

Death by misadventure
In medieval times, justice was slow -- literally. The court (or 'eyre') would travel around the country in a giant circuit. When the court was in session, the first thing they would demand is an account of all crimes that had occurred since the last court, which may have been 7 years ago, or 44 years ago!
Now, if you thought the purpose of this was to ensure justice was done, you get points for altruism but lose them for gullibility. The courts -- then as now -- would fine the miscreant (and sometimes the entire village) which was an important source of income for the government!
So in 1194, King Richard the Lionhearted -- trying to raise money to support his disastrous Crusades -- ordered that every village appoint three knights and a scribe to keep track of all crimes, which would then be reviewed by the next court. This was known as "keeping the pleas of the Crown" (Latin, custos placitorum coronae) from which the word "coroner" is derived.
Now, if that sounds like the role of the sheriff, you're probably right, except you'll know from Robin Hood that sheriffs were notoriously corrupt, and for a small contribution a crime would not be reported to the court. Coroners (or "Crowners" as they were known at the time) were an attempt to curb this, by having a separate person document the crime.
From the start, one of the key functions of the coroner was to investigate a sudden or mysterious death. Again, if you think that was to understand how the person died, or to figure out by whom, you've been watching too much CSI. One of the first acts of the Normans (after conquering England) was to pass the "murdrum" -- a huge fine levied against any community where a Norman was murdered. Thus, the coroner had to determine if the body was Saxon or Norman, and if the death was intentional or accidental. To that end, they could order an inquest, subpoena witnesses, hold a jury, and deliver a verdict. Much of this has been carried forward today.
They also had one other important function: To determine the object that caused the death. That is because the Normans also supplanted the Roman law of noxal surrender -- whereby animals or objects causing serious damage or death were given to the victim -- with "deo dandum" (literally, "to be given to God") which, in effect, meant they were forfeit to the Crown. (Usually, they were assessed a value that the accused had to pay to keep the item, so it was effectively just another tax.)
In 1340 they did away with the murdrum, and in 1846 they abolished the deodand. As courts became established there was no longer a need to "keep the pleas," and coroners increasingly focused on sudden deaths. However, historically this was never a medical role, and even today a coroner in England must have a degree and five years' experience in the medical or legal field. In the US and other colonies, there are a patchwork of laws -- many areas require a degree in forensic pathology, but other areas have no requirements whatsoever! Other countries
In the UK, a coroner can return one of 15 "verdicts":
- Death by natural causes
- Death by misadventure
- Accidental death
- Lawful killing (e.g. self-defense)
- Suicide
- Unlawful killing
- Occupational disease
- Drug dependence
- Non-dependent drug abuse
- Attempted abortion
- Self-induced abortion
- Disaster
- Still birth
- Self-neglect (for example, anorexia)
- Lack of care/neglect
They can also return an "open verdict" (cause not established) or a "narrative verdict" which makes no sense to me. (I don't have all the answers!!)
There is no effective difference between accidental death and one of misadventure, except that one sounds tragic and other sounds hilarious.

Olympic disappointment
I could have bought tickets for £295 each (or closing ceremony tickets for $655 each), but that's just crazy.
Crash and burn
It actually hurt quite a bit; I'd really opened myself up. In hindsight, I wish I'd done a million things differently, but in the end I'm sure it's for the best. As I said, I'm grateful just to know I *can* feel that way again, and now the trick is to find someone who feels the same about me.
In the meantime, however, I have the very practical problem that I've now cut off contact with everyone I was talking to, I don't have anyone in the "pipeline," and I have tickets to *four* events in the next week! I've invited friends, who are all busy, and I'm really going to kick myself if I waste these extra tickets.
P.S. Ben & Jerry's cookie dough ice cream contains wheat. Duh. I'm eating it anyway.

Summer is here
Next weekend I'm going to a wolf sanctuary, which turns out to be just up the street from my house in Reading.
The Rooftop Film Club has a number of outdoor movie screenings -- I have tickets to see Trollhunter, Big Lebowski, and Labyrinth.
The Queen's Diamond Jubilee is on 5 June, the Olympics 27 July-12 August, and Paralympics 29 August-9 September
Music-wise, I have tickets to Rumer, Paul Simon, and Paloma Faith, plus a revival of the musical, Ragtime.
If it's dry, I'll be attending Folk by the Oak again. (I thought about attending WOMAD, the World Music festival, but it is at the same time as the Olympics...)
Outside of London, I plan to go to the Bristol hot air balloon fiesta and the Edinburgh fringe festival, both in August.
Comedy includes Pajama Men and a staged reading of the Hitchhiker's Guide to the Galaxy.
And finally, I will be attending the Thames Festival, which marks the end of summer, on 9 September. :-(
Of course, those are only the things I already have tickets to. I'm sure there will be much more before the summer is out.

Feasts
And the son replied, "But father, in many years the sands of time will have refilled the well, stopping the water and erasing its very memory." But the king said, "We will mark the site of this well on our maps, and preserve our maps, so whenever you travel this route, you will be able to reopen the well and obtain the water that will sustain you on your journey."
So a festival is an appointment with the past, an encounter with an event that occurred in our history, but becomes part of our present and our future. It comes complete with instructions on how to re-open the well and access its waters. These were not "one time" gifts because these were not "one time" needs, and festivals serve not only as perpetual reminders, but as perpetual sources.
So it really doesn't matter if you celebrate the Jewish festivals, the Christian festivals, the American holidays, or just make up your own. The important thing is to mark and remember, to appreciate what has gone before and what is yet to come, to know that you are part of something bigger, and while you can always choose to cut yourself off, you can also always choose to reconnect. As I get older, I have really started to appreciate not only the circle of life, but how important those circles are in our life.

Completely besotted
Which, incidentally, is exactly what we did today.
In some sad, self-loathing way, I was actually hoping to find out our first date was just a fluke, that she couldn't possibly be as wonderful as I thought, or as lovely, and that I've been obsessing over her for nothing. However, in those terms, it was a spectacular failure. Not only was she just as pretty, but I went to her neighborhood and in the process of walking down the street, half a dozen people came over to say hello. And she'd only lived in that area for a couple of months! I've been in Reading for 9 months now and I can't think of a single person here who would recognise me, never mind say hello. :-(
Which brings me to the other major emotion I've been feeling: Inadequacy. It's funny, at some level I recognize how much I've accomplished in my life, but I don't derive any pride from it. On the contrary, it feels like it's no longer relevant. Years ago I took a personality profile (of one sort or another), and one of the things it said was that the clock started over every single day. I think that is absolutely true, and I wonder how that comes across.
In any case, I have no idea how she feels about me, or if anything will come of this, but the important thing is that she reminded me how dating is supposed to feel like. I've spent a lot of time with some really lovely people and I've certainly enjoyed every experience, but I haven't been "dating." So I've ended communication with everyone else I've been talking to, which wasn't easy but was necessary.
Watch this space.

Shavuot and cheesecake
1) Rosh Hashanah to listen to the shofar (horn)
2) Yom Kippur to repent and make atonement
3) Pesach (Passover) to eat unleavened bread
4) Sukkot to live in a tent
5) Shavuot to...uh...well, this one is a bit vague.
To be fair, all of these involve making sacrifices of meat, fruit, and bread, and three of the festivals (including Shavuot) involved going to the temple in Jerusalem (which, oddly, hadn't been built when the Old Testament was supposedly written). Unfortunately, the Romans destroyed the temple in 70 CE, and while all the other festivals had other things to keep them going, Shavuot was kind of forgotten.
Fortunately, the great sages managed to rescue it from obscurity. They argued that since Pesach represented the Jews fleeing Egypt, and Sukkot represented the Jews entering Israel, then Shavuot (which fell between them) must have been the day the Jews went to Mount Sinai and received the Bible from God. (That's a pretty big stretch, although not quite as big as when they literally interpreted the phrase, "the people were beneath the mountain" and therefore claimed the entire mountain lifted off the ground.)
Now, of course, it gets a bit weird. The sages then argued that during the day, the Jews would have been preparing a meal, slaughtering animals, and so forth. Then they went to Mount Sinai and accepted the Bible, including all the laws about keeping kosher, so that when they came back to their camp, they would not have been allowed to eat any of the meat. Therefore, they only ate the dairy products and went to bed.
From this we get two traditions around Shavuot: One is to stay up all night discussing the Bible; and the other is we eat cheesecake.
I probably won't stay up all night, but I will definitely eat cheesecake.
Here is the section of Leviticus 23 (King James Bible translation) that deals with the festivals. (Leviticus, the fifth book of the bible, was kind of a cliffs notes for the first four books, and even though it got a lot of stuff wrong, it summed up the holidays nicely.)
Passover:
5: In the fourteenth day of the first month at even [sundown] is the LORD's passover.
6: And on the fifteenth day of the same month is the feast of unleavened bread unto the LORD: seven days ye must eat unleavened bread.
7: In the first day ye shall have an holy convocation: ye shall do no servile work therein.
8: But ye shall offer an offering made by fire unto the LORD seven days: in the seventh day is an holy convocation: ye shall do no servile work therein.
...
Shavuot:
15: And ye shall count unto you from the morrow after the sabbath, from the day that ye brought the sheaf of the wave offering; seven sabbaths shall be complete:
16: Even unto the morrow after the seventh sabbath shall ye number fifty days; and ye shall offer a new meat offering unto the LORD.
...
21: And ye shall proclaim on the selfsame day, that it may be an holy convocation unto you: ye shall do no servile work therein: it shall be a statute for ever in all your dwellings throughout your generations.
Rosh Hashanah:
24: Speak unto the children of Israel, saying, In the seventh month, in the first day of the month, shall ye have a sabbath, a memorial of blowing of trumpets, an holy convocation.
25: Ye shall do no servile work therein: but ye shall offer an offering made by fire unto the LORD.
Yom Kippur:
27: Also on the tenth day of this seventh month there shall be a day of atonement: it shall be an holy convocation unto you; and ye shall afflict your souls, and offer an offering made by fire unto the LORD.
28: And ye shall do no work in that same day: for it is a day of atonement, to make an atonement for you before the LORD your God.
Sukkot:
39: Also in the fifteenth day of the seventh month, when ye have gathered in the fruit of the land, ye shall keep a feast unto the LORD seven days: on the first day shall be a sabbath, and on the eighth day shall be a sabbath.
42: Ye shall dwell in booths seven days; all that are Israelites born shall dwell in booths:
43: That your generations may know that I made the children of Israel to dwell in booths, when I brought them out of the land of Egypt: I am the LORD your God.
P.S. Oddly, Christians have tried to claim all of these festivals, with the idea that these were not annual events, but prophecies to be fulfilled by Christ. I don't get that at all. However, since Shavuot falls 50 days after Pesach, the Christians renamed it Pentecost, with something about the holy spirit. Christians=holy spirit comes to earth, Jews=cheesecake. 'Nuf said.
