Should I get my girlfriend a cookbook or new pair of kneepads for Valentine's Day?
take a friend you can gossip with
try different routes so you see new things are you indoors? watch tv
Imagine fun stuff, I guess.
That's called a monitored alarm system, if that's what you're asking.
Get one of those paddle balls. You know the wooden paddle with a rubber ball attached to a long rubber band to the paddle? Paddling the ball is fun while you walk. You MIGHT consider getting some roller blades or old fashioned roller skates and skating for exercise instead. It is a lot more fun and the weight of the skates will burn more calories than just walking. Running into things and especially cute guys would certainly spruce up your day.
