My health is very poor. A fleshed out version might run to 25 000 words. I'm not going to manage that. Worse than that, I don't really know how to write. They say one needs to write a million words to be any good, so the full project, learn to write, then come back and flesh it out, runs to 1 025 000 words.

Please have a go at fleshing it out yourself.

Even if you never publish it, you will have to commit to views about personal identity and how and well it survives the passage of decades. Perhaps, in thirty years time, you will rediscover your completed manuscript. You would get to look back at yourself looking forward and both compare who you are with who you thought you would become and compare the person you remembered with the author of the text. Have fun keeping track of how many of you there are.
