Those of us who grew up before computers take for granted a lot of basic mechanical skills. Who DIDN'T know how to change a tire, change the oil, set the timing, bleed the brakes, adjust the clutch, change the plugs, fix simple plumbing and electrical problems around the house etc etc That a lot of people still do these things is evident at your local Home Depot or AutoZone store.
But, since the rise of the internet, and computers, and software, and computer games, a lot of younger guys are helpless as girls out there when it comes to hands-on fixing stuff, or as noted even change a tire.
