It's worked very well for me for over 40 years. I used to have a few puffs after work on my commute home most work days. It was a great way to wind down after very stressful work days. By the time I got home I was no longer thinking about work, relaxed and ready to engage with the wife at her level. I don't go to the doctor unless I have pneumonia, bronchitis, other affliction or have injured myself. My last doctor visit was around 2003, I had developed pneumonia and needed antibiotics. Aspirin remedies most issues as they arise - muscular pain, joint pain, headaches, etc. Otherwise, I do not take medication. My BP dropped an average of 40-50pts after leaving the corporate world. Last checked last week at a dental cleaning, 109/70. I smoke a pack and a half a day, generally don't drink but will pound down a few when getting together with old friends. I catch a light buzz about once a day (5-6 hits or so) usually in the evening, spend too much time sitting on the sofa posting on POAL, sipping my covfefe. Essentially I have most bad habits they tell you not to do but I'm still in better shape than most of my peers. I'm 6'1" and 210lbs, i've been that weight +/-10lbs for 45 years. I eat like a horse, whatever I want. Same appetite as when I was 20. I drink a lot of milk ... 3 gallons a week avg. "I'm in good shape for the shape I'm in."
