In the scientific realm of street physiology, there's the normal strength that we expect from an average human being, and then there's 'old-man strength' something so erratic and profound that it's not even quantifiable. We're not even sure what causes old guys to have the strength of a Kryptonian. Perhaps it's all the years of seemingly infinite push-ups and curls that have forged their muscles with a layer of permanent muscle that acts as a forcefield. Old-man strength can been seen in several facets of society -- for example, have you ever tried to arm wrestle an old homeless guy? Exactly. The dude would literally stretch your arm from the tendon and then methodically rip it off without even thinking about it. The fact is, old-man strength is tangible entity -- something that could only be expressed fully through a spinning backfist KO. While Alaska doesn't have an athletic commission, apparently they do have an influx of older guys that can knock out young 'whipper snappers' with a single punch. Check out what happened at AK Beatdown, a non-profit event in which 100% of ticket sales went to building a combat sports academy in Juneau in order to provide kids with something to do in the frigid arctic of Alaska.
