So Claire and I were talking about this story the other day...go ahead, click the link and then come back...I'll wait...
I don't have the words...as a matter of fact, the statement that Claire and I were "talking about" the story is not exactly true...it was her telling me about it and me looking out the window in shock.
I think I dropped a "WHAT THE???"
And then the evolutionary biologist says it happens in about 1 in 400 fraternal twins?
And he says it happens because they are looking for someone who is more genetically different...suggesting that if you look like your mate/spouse, then you are more prone to be cheated on.
Or did I miss something?
Really makes the whole Swinger Scene a whole lot more scary.
