Wrong Picante. Whether you regenerate or not doesn't depend on your health level (unless you have adrenaline activated) but on your stamina level. Try it out if you don't believe me.

I did this research back at the end of F3 or somewhere in F4. I used to think it was health too. Then I wondered why I didn't recover one day while my HP was high enough. Then I saw it had to do with my Stamina.
