Agree with all of that. Still no reason not to be optimizing our environments a bit more than the usual person might. There are less obvious threats to respiratory health in the developed world but the ones that are left are probably more insidious e.g. radon gas, VOCs from paints. Having cooking fires sucks for the women tending them in the Third World but most family members probably aren't in the house/hut for most of the day. They're probably engaged in plenty of physical activity outdoors. We on the other hand are sitting in places with artificial florescent lights and are in the same spots on a consistent basis. We should: - have natural sunlight (using my magical heliostats) - run about more - be surrounded by plants (perhaps visits from cool animals) I should start a minor religion.
