My dad also did not make it to the Vape scene. Although a heavy smoker, it was Agent Orange that took him.
I believe he was progressive enough to at least have tried it if he had had the chance.
I, on the other hand, have now been vaping for about 2 years, 8 months. Sons are 30, 26 and a set of twins now 10. Also included are a couple of step-daughters, 13 and 19. The older one has vaped for a bit until the novelty wore off, although I'm pretty sure the 13 yo will get into it when her times comes.
All of them are glad the wife and I no longer smoke and don't see any problems with vaping!
