Bruises

Not going to show you a picture of it, but I've gotten a bruise on my leg.
I'm wondering whether it's only me, but whenever I have a bruise, I'll keep poking it...
Half of the time I'd have no idea how I'd gotten the bruise, but I'll definitely poke it.
Since I'm on the topic of injuries, I prefer injuries where the skin is still intact (Though I've yet to have any broken bones or dislocated joints, so I can't be sure... 'A')...
One reason is that, if you poke an open wound, it'd get worse, whereas if you poke a bruise, it wouldn't?
Hur I don't know.
