I know I'm probably going to die a vaper, too - but I am okay with that. It's better to burn out than fade away, regardless.

At this point, what time am I hoping to gain - a few extra years drooling allover myself in a nursing home?
I can totally identify with that love/hate relationship I had with smoking.
I felt guilty for cheating myself (and my loved ones) out of time they might have spent with me... in the past (when I would crawl out the back door for a nail), or in the future (due to a pre-mature death). I really *do* enjoy vaping, and based on purely anecdotal evidence - I think I feel better as a result of making the transition... BUT - I can't make a definitive statement like that as a business person because of (obvious) liability issues. My role, if I have one, is to discourage you from taking anyone's opinion at face value and encourage you to make whatever decision is best for you.
Every day a football player takes the field knowing a single hit could leave him paralyzed, but he does it anyway...
Every day mothers give birth to children despite the fact that it puts those same mothers at elevated risk of a wide variety of physical and emotional maladies (love you, ladies - y'all are the true givers)
Every day men and women undertake risks - nothing in life is certain or guaranteed - the best we can hope for is to make reasonable effort to ensure the moments that accumulate are meaningful, and that when we do go, they say "John lived a good life." Then, what will really matter?
