major in college? seriously? mine was how to become a starving artist. ('77 - '81) and I am a flaming success at it.
anecdote: when I was very young; maybe 7 yrs old, my Dad brought me to the hardware store where we picked out a dry cell battery; some wire; a switch; socket and light bulb. with which he showed me how to build an electrical circuit. the dude is a psychologist ... go figure ...
