Of all the unhealthy addictions in this nation I will never fault someone for being addicted to getting healthy... regardless of what method they use and I have a hard time imagining someone so petty that they can.

I agree, like other forms of exercise , including yoga. Having the time to get away from work, the grind at home etc. For myself a good cardio workout within my limitations makes me fell better. Some weights and pool time round it out.
