Can anyone here answer a question I have.
I was wondering what would happen to the brain if a way was found to halt
the ageing process. By this I mean prolonging life for ever, barring
accident, murder or suicide. I am not in any way knowledgeable about the
science of the brain, so forgive me for my mistakes, but I believe that the
brain cannot keep learning forever and also that brain-cells die and are not
replaced, while other cells are. This being the case it seems to me that if
we could 'live forever' after a long enough time we would simply become
vegetables as our brains lose their ability to think. Please could someone
tell me - how long would this take? How long before our personality
noticeably changed? How long before our IQ began to drop? Would it? Or,
have I made a fundamental mistake?
Any answers would be appreciated,
Yours,
Philip Harries
