King of Pain...

... is an Alanis Morissette song that fits the occasion quite well. Fundamental question:

Why on earth does a wee superficial graze hurt so much more than any fatal wound you are dealt?!?!?!

Right. I broke my foot recently. No, not true, I fell and suffered a hairline crack in a metatarsal, heavy bruising of that foot, and - a tiny graze, which now drives me mental.

And don't tell me anything about severed nerve ends or sensitivity of the skin or exposure or any of that kind of rubbish, I don't want to hear it.

It's because life is unfair and mean, that's why.
