Ughh that happens to me all the time!! Sometimes, I don't even need to *** my finger, I'll just squeeze it and blood comes out. I've always just tested on my left hand since I'm right-handed, so I've got a million holes in the fingers on my left hand...
Yeah that happens to me too where you can just randomly squeeze a finger and get it to bleed.
Creeps me out thinking that my fingers are that easy to get crap into. Working in an E.R. makes me paranoid about that. Whenever I test at work I hold pressure on the spot way longer just hoping that it doesn't stay "open" to the hospital world.
