Same here... Machinist, then commercial/industrial Carpenter, then welder/fabricator, back to commercial construction, back to Machining.
I also smoked and dipped tobacco up until 7/25/2012 which was the day I quit all that cold turkey.
My lungs will need 20yrs to heal from all that smoke, dust, and airborne coolant/metal particles. I was doing cardio 5 days a week until a year ago I started slacking off some. Now my gym is shutdown and so are the parks with jogging/walking trails, so I'm going to need to start exercising at home more often.
