Die of what? 10% of smokers get cancer, others get heart disease, COPD, Osteoarthritis, ... the list is long. You want to feel crappy, smell bad, and be tired all the time? Not to mention the cost financially then smoke up. It takes years off the end of your life.
It's not widely published but PROVEN that certain people carry a genetic code that will prevent them from EVER getting cancer from smoking.
Merv Griffin died at age 82, was in good health his entire life and smoked ever day.
It's all about the risks you are willing to take with your own life. But the real question you and only you can answer is are the "benefits" (What ever that may be) of smoking greater than the potential risks?
