We live in a complacent, lazy, inactive, society. Whats the obecity rate in the States these days? Or the U.K for that matter.
This is another topic altogether. If people simply ate sensibly, exercised for an hour a week, used the stairs and walked short distances daily, obesity rates would be significantly lower. I don't think that is even conviction or dedication, it's so easy to exercise and eat well.
Training regularly is very important indeed, however, having an opportunity to reflect upon your experiences and free your mind of clutter is important for progress in MA too.
