Learning new things

I just downloaded a new app onto my iPhone, a popular calorie counter. When I told my friend I had downloaded it, she said, “Why would you do that? You don’t need it. You’re as thin as you need to be.”
“So I can help other people,” I replied.
“Oh, I see,” she said.

Our exchange got me thinking about how I’m just interested in learning new things, which make sense in my case, because tai chi is all about learning new things. My friend’s assumption was I wanted the app for myself, that I needed, or thought I needed, to lose weight. But I really just want to know how that stuff works; in this case measuring, categorizing and inventorying nutritional information. You might like the app, too, whether you need it or not. You just be able to help someone. MyFitnessPal at the App Store.
