I'm Glad I'm the Oldest (Not That There Is Anything Wrong with That)
Apparently this phenomenon is not new. It's called the Birth Order Effect (men with older brothers are more likely to be homosexual) and I found articles as far back as 2000 about it. This latest study took adopted brothers into account and found that it's only true of biological brothers.
I just thought it was something funny to rib younger brothers about.
BTW, Which one of you Quinns is younger?
