Youre right about the lifestyle change, I should have included that. Also yes, he is in fact teaching Honors Anatomy and Physiology to seniors in high school. Another thing he taught us is that blood is blue in veins, which it actually is not. I think he is just very outdated, but he doesn't seem that old, maybe 50ish. I would try to start recording but the school policy on electronics is not friendly, if I was caught I would be suspended. I will try to record the audio on my phone if he starts talking about obesity again though and I'll post it here.
