>>9831471Fun fact: because your limbs half-hazardly evolved out of the spines of fish fins, you’re lower arms and legs are composed of two bones held together with the biological equivalent to duct-tape, instead of being just a straight forward series of ball joints.
This means it relatively easy if you fall, twist, or pull in a sufficiently wrong way to tear right through the cartilage and ligaments holding those two bone together. My dad had this happen to him a few years back and it apparently sucked balls and took a long-ass time to heal.
So remember, don’t rely on evolution to design your body for you, evolution is a lazy and often very dumb idio-savant of an engineer.
