I also have a diabetic friend, and yes, I was exaggerating. I suppose I should be careful, as its probably not obvious enough that everyone would realize I was.

I agree the information is interesting, but the collecting is a huge hassle. That's my problem with this whole thing. If I go on a day-hike, I don't want to be pulling out my notebook constantly to report my energy levels. It kills the experience, makes it more about me than nature or the hike itself. As I said in another comment, if I could passively collect all this information, it'd be great to have, but I feel like the cost of collecting it outweighs its usefulness in most cases. But I'll certainly grant you that the equation varies per person.
