Arm bump.. Am I just crazy?!?!

AJAdkins

I seem to be very obsessed with this pouch of fat just after my wrist going up my arm. I've noticed its shrinking, but on days that I slip up and eat bad I swear that it puffs up again. Does anyone else have this?!?! What causes fat to go there?! I've seen heavy people with slim forearms and granted I realize everyone isn't the same, I'm just so curious about it.
Does anyone else deal with this?!? Or have noticed this.. or am I just crazy? lol
