..........and what about my teeth ?...is there is soupcon of a difference between my top teeth and my bottom teeth due to gravity luff and joy ?(and I don't mean that my arse has teeth !!)
How big you are is determined by your genes so you wouldn't change much, but if it was maintained for a long time it would definitely affect evolution.Gravity gives you a penalty for being taller - the structure required to support yourself and the likelyhood of you breaking when you fall over, and there are advantages in being tall - you can reach further, see further etc. So large creatures presently limited by their engineering would probably evolve to be taller, if nothing else (like air pressure) changed. It would mean that birds could evolve considerably bigger and trees taller.
