Deadly Frisbee

Ok so i know i get bruised super easy and stuff but this is just ridiculous. I showed you a couple weeks ago (June 8th if you want to see the pic) about my bruised hand following a relatively mild game of frisbee. Well we played again last night when everyone was over for Father's Day.....and guess what happened to the *other* hand in the exact same spot?! Not nearly as bad but still...do i have some kind of bleeding/bruising disorder? I can't remember a time when i didn't have multiple bruises all over me. Mostly my legs, but i bruise super easy.
