The real trick would be to regrow memories in such a way that they are
better and more pleasant than the original memories. Think of the market
for such a technology. Surely there are buttloads of money to be made by
the first person who masters it.
Memory is a puzzle. According to my very limited understanding (to which I
eagerly invite instruction from the local groksters) every time we access a
memory, we actually rewrite it in a sense. So would not some memories be
subject to drift, from multiple accesses?
Reason I am interested: I am writing a book about career events that
happened a long time ago, but I fear that I am remembering old times as much
more pleasant than they actually were at the time. My recollections are
about happy, funny, interesting times, whereas at the time I was probably
annoyed, frustrated and bored at least part of the time. By forgetting the
bad and fondly recalling the good stuff, my own memories paint the past in a
far more favorable light than they deserve perhaps.
I don't know how to compensate for that, or even if I would want to.
