There was a post about this on another board a few weeks ago and I found this article today:
http://shine.yahoo.com/channel/sex/how-birth-order-determines-your-romantic-compatibility-1441180/So I was wondering what you gals think. Personally I don't really think it matters. When you think of all the other things that make a person who they are birth order seems pretty low on the list. I'm the oldest with one younger brother and BF has a younger sister and older brother (according to this we aren't a good match so maybe that makes me bias against it

) But I don't really get why anyone wastes time "researching" (i really don't know how credible any of it is) when in real life it probably matters very little if at all.
