How Different Are Girls’ and Boys’ Brains?

It’s a favorite question of ours…okay, of mine (i.e. Lo’s). And my personal answer is that yes, there are differences, but not as many or as great as our culture likes to assume or presume.

Guy A: How are things going with your new baby? Guy B: Oh, you know, that’s pretty much Amy’s deal. We swear to god, this is an exact transcript of a conversation that took place between a friend of ours and one of his college buddies. Sure, it’s an extreme example, but it’s not an […]

The Discovery Channel is in the middle of airing a series called Curiosity.
