Turnover

Today is day number 13,425 in my life, which is the (arbitrarily estimated) half way point. In another 13,425 days, I'd better have things all wrapped up.

I might call it a halflife, but that suggests I'm an exponentially decaying process, rather than a constant one with a fixed endpoint. It might make an amusing habit to celebrate each remaining halving of time, though. By the end every day will be a party!

At least half the things I've wanted to do in life I've done by now, I think; maybe more? I've certainly done more than enough of the things I didn't want to do. Half again sounds very tiring. If I were inclined to think of life in terms of doing rather than being, or aspiring rather than accepting, I'd think this a day for reflection on achievements, or something.

Mostly half a life has left me very confused though, and increasingly inclined to accept things and be happy for each new incomprehensible day, each friendly conversation. Nobody really has any idea what's going on.

I saw a film last night about dreams, finitude, loss, airplanes and love. A character in it said that engineers only have ten years of creative work in them. Back-dating, I guess that means I'm done with creative engineering! A shame, I had a few neat things planned still :)

I'm going to buy myself a delicious apple turnover now, and go visit baby Sebastian, who just turned one and absolutely cannot count to 13,425 yet. I expect he'll make cute gurgling and shrieking noises.

I recently read something about Gompertz' Law, or more accurately the Gompertz-Makeham law:

Turns out it's actually neither an exponentially decaying process nor a constant one with a fixed endpoint: it's something in between. From adulthood on it's essentially a process in which the probability of dying in a given year increases exponentially with time (flat probability would be the "half-life" scenario). There may or may not be some kind of modification of the curve at very advanced ages.
