Boobs! -Just kidding, there is more to being a woman than having boobs, obviously....
I think it's relative, Personally, I think being a woman has it's good qualities and bad qualities.
I thought to myself, In my next life time, would I want to be a woman or man, and I definetly still would want to be a woman; even though I would have to deal with dreadful periods ever month.
If you were a man, you could not get away with a lot of things women could get away with, like playing the steriotypical roles of a "dumb woman" just because you could care less about the conversation anyway, This would appear as being "cute" or typical, I guess.
Actually this question is alot harder to answer than it seems. The answers couldn't possibly be cut and dry, It would require a lot of in depth thinking, that I don't have time for at this moment. It's a great question, and I believe there are a lot of good things about being a woman.
Like having Boobs!
