The older I get, the easier it is to wake up. Granted, my joints are all seized up and my feet don’t work for 30 minutes, but 5 to 10 minutes before the alarm my eyes lever wide and getting back to sleep is impossible. If I had problems getting up, though, I might consider this Sonic Alert Super Shaker Bed Vibrator, a $40 unit that clamps onto your bedframe and vibrates you into wakefulness or sexual release, whichever comes first. It even has a built-in temperature sensor to protect the unit from overheating (your sexual fever is your own problem, however).
