Not being in the sun for more than three decades means I look (skin) years younger. (Who goes home before dark?) People just don't believe my age. When they ask "how?" I just tell them "mushrooms"
But slumping over the keyboard for the same amount of time has really messed up my neck/back. Who cares about carpal tunnel when your hand goes numb? Take breaks! Stretch! Attend meetings. (See... they are good for something ;-))
Hey, I forgot my "programming accident". While eating lunch at the workplace cafeteria the answer to a difficult gnawing problem finally came to me in a flash. Unfortunately "Ahh!" was immediately followed by "Ow!" as I finished closing my mouth on the latest bite, only having forgotten to remove fork first. Cow-orkers were not as interested in the discovered solution as much as how many more pieces of the front tooth I was going to discover.
Fortunately dentistry has this marvelous 'patch' procedure they call 'crowns'. And it only took three tries before the biting program stopped throwing faults!
