Not really i usually notice right away if i scratch my hand or something.
It's not so much fun when you wake up on a sunday afternoon with a massive headace and your arm hurts. Then you look at your arm to notice half the thing's covered in scratches. Then the thought "how did i get home last night" pops up and you cant answer it. And all you know is that you're deffenetly about to have an interesting day.
Am i right!? -no? No that's just me?
