As far as I know only some broken bones (legs) and he will or already did fully recover (was not as bad as it looked and sound like)
Yep, he is recovering. He is dutch by the way. Pretty pointless to mention the pain factor. You can recover 100% but in the process faint of pain, just ask around....
A friend of mine had footage of himself making that noise after pounding in. (stalled his reserve). I taped over it immediately because I never wanted to hear or see it again.
