Popular Mechanics asks:

Are hands-on skills — building things, fixing things, operating machines and so on — really in decline?

Short answer: Yes.  At least for me.  Sure, I can program computer code, replace a hard drive, change a tire and a few other things.  But for the most part, if you ask me to nail one 2-by-4 to another 2-by-4 (is that the right phrase – "2-by-4"?), I’m as useless as an umbrella in the desert.
