[TheForge] A different needle question

[Bruce .]

My Uncle Harry worked in construction-related fields.  Last job he had he
was customizing commuter jet aircraft for the sheiks of Araby, etc.  Late
in life he got lung cancer.  (This was after he got colon cancer and had a
colonoscopy.)  Doctors said it was a classic case of "smoker's lung".  He'd
never smoked a day in his life ,,, ,

Be careful!
