The palm of the hand HAS to be the worst source of blood...right?

[Murk]

Is there something anatomically "perfect" about the hand, where you get a reliable blood supply but there's no danger of bleeding out? Do the wounds heal more quickly or reliably?

This got me thinking what the perfect location would be, and my money is on the inside of the nose.

- Very easy to make it bleed, I can do it with my own fingernail!
- Bleeds a lot and easy to keep the wound open, so reliable supply
- but also easy to stop the bleeding when you want, so not very dangerous.
- Easy to aim.
- I've never heard of a nosebleed getting infected, it doesn't even need to get bandaged.
- Not on the outside of your skin so it won't touch anything while it heals

And as a cinematic bonus:
- Easy to hide fake blood capsules on stage.
- Very symbolic: close to the brain!
- Properly gross.
