Well, that's your choice. IMO, though, logically, some toxins must be far less harmless than others, and the ones we can actually do something about are such as those toxins found in cooked foods. Air-pollution is more difficult to get rid of on a personal basis, and there's far less scientific data supporting its harm by comparison to cooked foods. Simply put, we have all sorts of toxins affecting us:- some affect most individuals in a harmless way(eg:- most are definitely not affected by electromagnetic sensitivity), and we should concentrate on those toxins that affect us on an immediate basis. Granted, if one is living next to some over-polluted swamp etc., one has something to worry about, but for the vast majority, it's otherwise best to just reduce the basic, most common negative effects on health such as reducing smoking, cooking foods etc.
