For what it's worth, no matter how many chromosomes, X or Y, I can't get my head around technology. Right from the early video recorders I had no idea how to program it, the washing machine wouldn't look out of place on the flight deck of the Starship Enterprise. Sat-Navs are evil, they make you lose your temper. If it's a gizmo that has to be programmed, forget it. I had a smart phone for three months before using it, next door's 14 year old got it going in about the same time that he can complete a Rubic's cube.
I have never seen Bookface, Twitter Insta-wotsits and a dozen others. Things like Pay-Pal, Apps, barcode are a foreign language, either Gobble-de-Gook or Gibberish.
