If I track it in a spreadsheet, it should count as work

My work place is participating in the American Cancer Society's Active for Life program. Basically, we form teams, and each team member sets a goal for the number of "points" one will accumulate over a 10 week program. Points come from the number of activity minutes (exercise), drinking water, and making healthy nutritional choices. The point isn't to have the most points, but rather that everyone makes his/her own realistic goal and tries to stick to it.

Everyone's getting into it. It's fun to hear everyone celebrating the good things that they're doing (drinking more water, eating more fruits and veggies), rather than condeming themselves for what they should not have done (oh, I'm so bad; I ate 3 M&M's).
