In my 70s I figured out what to quit not doctors. I quit those things that give pain....trial and error. (Quit smoking 40+ years ago because I couldn’t climb the hills while deer hunting without huffing and puffing)
I hear you. I did two packs a day for 30 years. Once I started to see and feel the cumulative (non-cancerous so far, knock on wood) effects, my doctor put the fear of God in me and I switched to vaping. I figured my doc would light into me for doing that, but he approved. He said he had more patients quit tobacco with e-cigs than all the Chantix he ever prescribed.
