Since I eat in a way that's sort of counter to conventional wisdom, and read a lot of blogs about it, I also get exposed to quite a few other ideas that run counter to conventional wisdom. (Earthing! Oil pulling! Never washing your hair! Brushing your teeth with dirt! Avoiding plastics and microwaves and sunscreens and insect repellent!)
Some of these things I tentatively buy into, and others I tentatively do not. But I've been reading a lot recently about how playing is a fundamental human need. I don't know if softball really qualifies as creative expression, but after two successful games of it now, I gotta say, it beats the heck out of most other forms of exercise.
