>>Considering all the drugs and alcohol he has consumed over the years, he has a remarkably good memory.

>I was thinking about it. I suspect that most of these autobiographies are written with the help of many people. That is, they know who was there at the time and maybe remembers things better. Especially when they write about - almost exact - the conversation they had. Maybe it is me; but I don't remember the conversations that far back. Or, even more recent :)

I'm writing one, slowly, since twelve years ago. It's amazing how different periods are covered with memory clues. For last years of elementary and all of high school I have my then diaries - which then cover only what I wrote down and nothing else. In other cases, I self.memory.refresh() from photographs or various bits of news, the things which happened so important that I remember where I heard them (Gagarin - kindergarten; Armstrong - camping on Adriatic; 9/11, freshly unemployed, just sitting and sifting through ads, daughter called from DC; murder of prime minister Đinđić, going to a tavern with the Siriusware gang in Taos; London bomb, having breakfast in a Ramada on Manhattan). Now it's the eighties, from which I preserved very little paperwork, and what computer I had used cassettes - which I mostly transferred to disk in the nineties but then lost the floppies; and the nineties, when I didn't have a permanent PC of my own, but always had some box from the office, and it would often be mine just for a week or two and then be sold and I'd get a new one in another week or two. Whatever I had then had to be kept on the floppies, and I managed to read about one third of them, the rest were DDHD, formatted to 720K, which no bios now would agree to read. The true HD still kept. What I had on 3,5" proved to be far less reliable and I mostly don't have them anymore.
The true electronic record begins with 1998, when I finally started an affordable web connection at home, and had a box of my own - still owned by the office, but then I owned 40% of that, so I now have gigabytes of emails in a continuous line since then, and lots of various documents. The true continuity began in june 2000, when I finally bought a digital camera. Mind you, I had thousands of photos from before, but I didn't even preserve all the negatives; I'd guess I found about 80% of them. And reshot them digitally, so now I have photos since I was born, all in this PC (plus partial copy of archives at childrens' disks), but even there, the eighties and the nineties are quite thin. Mostly for economical reasons, the family grew faster than the income... so I didn't think of finding time to write things down, and also didn't find it important enough to make more photos.
