I am 53 and have seen alot of cartio specialsists. Non of them are
sure but the all have the same believe middle european jewish
background. I am not jewish. I was told it was chemicals in cigs
(agent orange is a chemical) I have found that when I do painting or
work with chemicals around the house attacks happen. So u have your
guy and I have several of mine. I don't think they care or will ever
let us now.

P.S. I have friends that have it from nam and never ever smoked cigs
