On a gloomy Friday:
Q? how do you know you're getting old?
A When you spend more than a minute skimming the obits for your year in the college alumni magazine.
A When you can identify almost all the obsolete skills on this list (Thanks to Ari at The Edge of the American West.) (Debugging EBCDIC core dumps should be on there.) Wood burning kits!!--I remember when my sister got one. And yes, darning a sock is one.
