And two weeks later, when Zim is gone for the season with a musle pull, shoulder strain, or plantar fasciitis?
This is the glaring one for me. Although I thought the last time he got really hurt (a few seasons ago) he tore the WHOLE plantaris muscle off the bone, which ironically, is the best "cure" for plantar fasciitis. I believe that all the other "fixes" don't really fix the issue, but tearing the whole thing off is a longer recovery, but allows the muscle to essentially repair itself "longer" than it then can extend further without tearing again.
Also, I am not a doctor, not a nurse, not even some body who works near a hospital/medical practice so I could be playing parcheesi in a game of chess.
