Can't find it now, I am sorry. But I remember the number 2^8000 or there about bytes, mentioned a few years ago as an estimation by some scientist. Neurologist. Now it is impossible to find it, since Google can't search "2^8* ... bytes ... brains" type of a string. Or some regular expressions or something.

Are you saying that they are wrong when they say that womb environment impacts intelligence and sexual preference

I am saying, that there is at the most a very tiny amount of the information flow, even if the womb can make you smarter or dumber. If a lightning strikes and makes somebody a 10 IQ points smarter - what I can see as a possibility - the amount of information by the thunder is about zero.
