Does anyone get headaches from breathing exhaust all day??? Is it possible that it may cause memory loss??? My friend has mowed 8-10 hrs / day for several years and gets headaches often. Also it seems that his short term memory is fading quickly. I have asked him about it and he says that he has noticed that as well because he forgets things very quickly. (No, he doesnt do drugs). Does anyone know the long term repercussions of breathing fumes all day long?
