I read some of the comments, too, and the one I don't get THE MOST (out of a whole lot of head-scratchers) was, "Some 30 year old must've made this decision."

Huh? In this context, is 30 too old or too young to make informed decisions? What does being 30 have to do with anything? I really don't understand that comment, and find it a very, very bizarre age to choose, unless the person posted was 16 and saying 30 is ancient...
