Are you serious? Most men are lousy multi taskers? The good hearing thing is a different issue. It's not that men doens't hear - they are listenting to what is in their heads on to what is being spoken (which they listen to like reading a new paper - read the first sentce and engage or not).
As for collecting thigs, I don't beleive that men do this more or less.
Actually I wonder if Men's feild of vision this is replicated in subject interest. Men seem to like to know a HUGE amount about specalist subjects - like football, bike engines, or geeky sides of subjects.....
I did some research on razors at one point and sat through a futurlogy lecture on technology - persumably men like langue that make the experience - so having a new gismo is not enough, they need to have technical descriptors. If you give a peice of new technology to a couple, the male will learn how to use it and keep that knowledge to themselves, women learn then share with the family.
Gender devides much more than anatomy....
