Poisoning & Anti Depressants
It is well established now that oil fumes in the cabin can poison anybody either in one big hit or over a period of time.
The general effect is to make that person feel ill and because they don't know how or why they got to feel so unwell, they tend to feel 'depressed'.
They eventually go to the doctor and mention the word 'depression'. Most doctors are still in denial about the ill health effects of breathing heated engine oils which contain toxic chemicals including organo phosphates and in their eagerness to 'help' and get on to the next patient......a course of anti depressants is prescribed.
So now we have chemicals already in the body being treated with more chemicals, which at best will mask the problem but can never cure it.
I know because I have been there, but I refused to take the anti depressants when I told the doctor that I wasn't 'depressed' and after reading the side effects!
