And another thing (waggles finger humorously at Lwien), you take 1.35 hits off that PD per day, right?
1.35 hits? Where'd ya get that from? I go from 3/4 to one stem a night. A few days ago, I got some over-the-top bud that worked on a half a stem for me. I get 5 hits per stem.
For me, any vape being on for 24/7 for four years (and still have it working and providing me the most in efficient vapor, regardless of having to put in a few retaining rings or not), is good enough for me. And I don't see how one who takes more hits than I, would cause additional wear and tear.
The one issue I do have, and that I have mentioned previously, is my concern of breathing in the fumes from charred wood over the long haul. That, I think, could be a health concern due to fumes and smoke from burning wood being a carcinogen. On the other hand, I would never think about not enjoying a warm fireplace or campfire. For me, I would much rather have a cleaner air path, especially at my age, and is the reason that I'm seriously contemplating an LSV.
With all that being said though, I really do wear my "ultimate minimalist user" badge proudly, and I firmly believe that the main contributor to this is my super efficient PD. I have no doubt that the LSV will cause my usage to increase.
I'm rather fond of that warm piece of cherry wood. It's become a comforting friend for more than a few years and still is to this day.
