Yeah because that people never eat something delicious like BigMac, French Fries, and coke lol. We need to change lifestyle and live in the village with fresh air to improve our life quality, but I don't see what's the point of we live that long if we can't take care ourselves anymore and just become a burden to our family.
I am not an expert, so I can't comment on the effect which processed food can have on longevity. That said, I don't know whether living in villages can shield you from pollution. With advancement in transportation and industry, there is no area within the earth which is not polluted. Even areas bereft of human inhabitation, such as Antarctica are polluted.
You are right, no place that not polluted, but atleast there are some place that have cleaner air than urban areas. I think it can make us be healthier and our age can be little longer.
