Dunno how they know, though, since he was also a heavy smoker.
There are millions of $$ still left in the Asbestoes law suit pool that are unclaimed. Perhaps the McQueen estate lawyers can go get some of it. It’s free money
I think his dad worked around asbestos as well.
His exposure was to a very identifiable type of asbestos used in insulating boiler joints and pipes.. Those people exposed to that should get checked every six months, IMHO.
