You need to use both hands and both feet to drive a manual transmission car. Kids today are good at using all their fingers on their smartphones and game consoles, but not much from the rest of their bodies.
When the army has trouble recruiting because kids don't know how to throw a ball or run very fast, then we have a problem.

My shoulder has gotten to the point that throwing more than a few yards is out of the question. Would be useless with a grenade unless I had good cover.
