[SaF] Left Handed-ness

[PeaceNsolace]

Has anyone read any good material, online or otherwise, relating to the 
scientific phenomenon of left-handedness?    Here's why I ask:  Although only 
31, I have always seemed to date left handed men, with no exceptions. And 
it's not intentional. As I look back, even into my teens, they were all 
lefties as well.  I even married (separated now) a left handed man.  Anyone 
have any good info?

TIA!!!  Peace
