It’s my belief that was the cause of my brother’s cancer in his face.
He loaded gravel trucks 5 days a week, 10 hours a day.
It was my thought that the angle of the windshield sided in burning his face
I believe it.
Good buddy of mine moved to Virginia and drove a truck for 18 years hanging his arm out the window.
Ended up with cancer. Died 7 years ago.
