A dynamic worth considering for application elsewhere is how UFC-style MMA is less unhealthy than boxing because it’s less restrained – even if a hold proceeds to completion without tapping, it’ll just mean a second of unconsciousness or a greenstick fracture that we trivially know how to heal, or at worst a baseball injury-style dislocation or tear; the ability to strike people you’ve taken down just means fights get called for obvious dominance more; meanwhile in boxing things are oriented towards a victory condition of inflicting brain trauma on your opponent
