What makes a man a man? (C. Aznavour)

Recently I realized that holidays are coming through (just before they finish, but better late than never). Good indicators are usually that old 'fun' things revive, like cooking, knitting, building things, decorating.. in short, everything that does not involve computers or out of the house communication. So I feel a bit weird, noticing that these activities stunningly fit to the classical stereotype of a 'housewife' :)
This put me on the question as to which degree the old stereotypes about men and women are still alive/natural/valid? In the end I could not really say what makes someone 'classify' as 'man' or 'woman' (biology excluded). Any ideas?
