Give me some credit, I just said put some maximum on pain, not remove it. Yes it'd be nice to recover from damage better but that doesn't help when you are being predated on, like when there is a torturer to make sure you don't recover or when a parasite like the Ichneumon wasp has its whole lifecycle dependent on eating a paralyzed creature alive from the inside out. If you want a discussion please be charitable, it's no fun if you seem to assume I didn't think at all.
