The last time I "gave up" smoking, I said to the doctor that I was expecting to get less winter colds. She said I was completely wrong, and that I should expect to get everything that was going around; that tobacco smokers maintain a lung environment that is hostile to anything living, including microbes, and that quitters can expect to catch everything that's going.
I have no idea whether that was true. But I'm still standing - yeah, yeah, yeah.
I haven't started smoking again, despite the potential health benefits associated with smoking.
I have known asthmatics that told me that smoking tobacco relieved their symptoms. But please don't take these remarks as advice to take up (or maintain) smoking! My comments were supposed to be taken as ironic.
If you remove an N95 in a smokey environment, you’ll immediately smell the smoke, while you didn’t before you removed it.
Exception: if someone is close enough to hit you with droplets when they speak (a foot or so), then a procedure mask is better than nothing.
