Alcohol kills brain cells slowly, but that never bothered me because I’m not in a hurry.
Actually I think that a little of what you fancy, in moderation, does you more good than harm.
As to killing brain cells, the general anaesthetic I had over 10 years ago destroyed more of my brain than all of the vodka I’ve drunk my entire life!
I was stupid for at least a year; couldn’t remember things; couldn’t solve my crosswords; and was exhausted all the time.
So the next time I need an operation, to do less harm, I think I’ll ask them to knock me out the old fashioned way, with a bottle of vodka!
