I can sure you they eat organic foods, they don't smoke cigarettes or weed, they don't have unprotected sex multiple times a week/month with multiple partners, they drink little or no alcohol, they don't use microwaves. They don't take prescription* drugs! The list is endless, basically they dont do anything the media encourges us to! They probably live places with the cleanest air (tazmania i hear has the best air quality) so research. If you didnt/don't do any or many of these you should be one of the last of billions to die :) if they don't kill you systematically that is...
