You may surprise yourself on how much exercise you can get in a day if you don't rely on gadgets or gizmos.

- For example, you may work your mind and soul if you have classes in the morning (or you may read/do puzzles/etc.).

- Upon finishing this activity, you may find a sudden--depending on the weather--urge to go play with water balloons.  At this rate, you may find out that you severely lack:  upper body strength, a decent caliber in aiming, any skill whatsoever in catching flying objects being thrown at you, or some combination of the three.

- Afterwards, you may find that you need to buy an item from your nearest grocery store; instead of driving, one of you may have the sudden urge to bike.  Because you thought impulsively, you realize as you glide down the hill that it's going to be one painful ride back up the hill.  Thus, you exercise your lower body.

- Finally, after such an eventful day, you go to bed early.

Voila!  A perfect, fun schedule.
