You start to observe speed limits. Once, you even let an old lady into a line of traffic. You stop to think and sometimes forget to start again. You appreciate the luxury of a nap in front of the tv. You start to grow pleased with your increasingly pear-shaped figure, finding it both attractive and aerodynamically sound.
Work becomes more fun and fun becomes more work.
You have a favorite, comfortable chair from which it is very difficult to remove you. You start reading the ads for Hemorrhoids, Constipation, Hair Loss, and various pain relievers. You begin buying the stuff - worse, it helps. You turn out the lights for economic reasons instead of romantic ones. You can no longer help the kids with their homework.
