Just as the paleo community has arrogantly—but I believe correctly—labeled a plethora of diseases “neolithic” (such as the whole category of autoimmune diseases, many different cancers, many mental health afflictions, livestock borne illnesses), I believe the same logic can be applied to many modern injuries, one of which I will speak of here.
Turning one’s ankle is the acute injury that easily impairs a neolithic human when one encounters a root elevated suburban sidewalk, or an unforeseen ditch or hole. Such traps are not uncommon in artificial topographies, but they are occasionally overlooked by the absent-minded, body unaware people we have become. This is one relative weakness we probably have as compared to our migratory ancestors, who would have had to be much more aware of pitfalls waiting beneath a bush or alongside a stretch of valley, as their entire livelihood would be at stake if an accident did befall them. Perhaps more importantly: such a scabrous and cattywampus landscape that hadn’t been preformatted for large machines and human walking alike would have toned paleolithic man’s joints—especially ankles, knees, and hips—to easily absorb the occasional indent or misstep without any major bodily response such as inflammation.
I’m sure there are many other acute injuries that occur as a result of the imposed and supposed neolithic lifestyle that we endure.
A tangential aside: as in the case of a swollen ankle or other acutely injured joint, isn’t the bodies response of causing the swelling something that should be left alone, not padded with the artificial invention of frozen water? I am no expert on these matters obviously, but I have learned to put a certain amount of trust in the body’s processes.
