bridxb,
I would agree that a few people know all about contaminated air; but I know from bitter experience that you would find most aircrew and passengers are desperate to know what stops them from doing their jobs / causing their serious ill health for years on end.
Especially when there are simple ways of preventing it.
Wouldn't you be desperate to know what wrecked your life?
The answer is under our noses and somebody needs to tell the people.
