Re: Harsh smoke
I don't know that it necessarily has to do with them smoking cigs. I was smoking with a couple of friends last night and neither of them smoke anything other than hookah, same as me. But they were able to get past the harsh smoke easier than I was for some reason, and I'm the one that has smoked more than them.
I think Demonix has a point, more experience means you know when it needs maintaining sooner.
