How about channeling some of this taunting concern and apparent knowledge into posting some good rules of thumb on some minimum exercise requirements and diet do's and don'ts.

Just keep in mind that we can't all be marathon runners. What would be some minimum criteria that the weakest link among us could do to tip the meter towards a healthier lifestyle and then maintain that?

I try and walk 30 minutes, at least 4 days a week and genereally watch what I eat. I don't drink or smoke. Is that enough, or do I have to be a total gym geek?
