What's your worst experience with pain?
I'll admit, I've never broken a bone in my body, never had any kind of diesese, never been stung by bees (ants are one thing :p) but I've lost my sight, had those little pin needles (about six) all the way in on my toes from sliding my foot across the carpet, and the worst sinus headaches you could imagine. most temporary things likes stings, breaks, etc. all have one thing in common; they will eventually heal (regardless of you keeping that limb) allergies and sinus problem stay with you almost forever.
So what's probably the worst kind of pain you've had (lemons and papercuts are mean :()
