They die of a bad conscience. We have to be able to make a judgement. We will do many things to keep us in the comfort zone. You will acclimate yourself to a hot climate if you face it without an air conditioner. Your flesh will always be screaming for the comfort zone when you begin sleeping night after night with an air conditioner blowing on you.
Many sicknesses are a result of our rooms full of positive ions when all the windows are shut.
Breathing the same air continually is deadly. If we have an air conditioner and we don't know when to turn it on and when to keep it off, we'll destroy our children. We'll never see the third generation. We need to train our children in everything, even in the use of toilet paper. We could be guilty of 2nd or 3rd degree murder if we cook vegetables that shouldn't be.
