Obviously, there are stress reliefs that don't carry a risk of giving you lung cancer. I'll take those, thanks.
I only meant to point out that many people in affluent western countries smoke, over eat, drink excessively and do other physically unhealthy things (because they have the money) in order to reduce mental and emotional stress. If we could reduce stress in general then we'd probably live longer, healthier lives.
General social issues lead to general health issues.
