is there a need for it?

Its like the Pringles commercial. "Once you pop you just cant stop" I think unless you have a really good moral reason not to do it...you will.

Yep, there is a need. It's a stress reliever. And that's all I got to say.

Overpopulated in what regard? I wouldn't make that assumption until there are people inhabiting every inch of the Earth. Could I go without it for the rest of my life? No way Jose! Long live the solitary tear!!

Well, I think one could go without it, but I'm not gonna be the one to find out.

^^^ I think we got the freak of the week. LOL
