Vibrating Wrist Watch Reminder
I would like to see some company make a wrist watch that could be set to alarm every 15 minutes, or every 4 hours, or whatever intervals were needed. It should vibrate rather than sound so that it would remain a private matter to the individual and also would not disturb others. It could be set to vibrate every 15 minutes to remind you to tighten your stomach muscles, or whatever muscles needed to be exercised on a regular basis. Or it could be set for every 4 hours, 6 hours, or whatever intervals you needed to remember to take your medications.
