It is such "stupid" ludicrous thread: smoking whatever and bicycling don't mix
Why would any body fill their very fragile lungs with smoke?
Particularly knowing what we know today!
Aside from the fact that cigars, pipes, or cigarette smoke is dangerous and really stinks!
Well, most cigar and pipe smokers don't inhale, but still, they're ingesting carbon monoxide, and CO bonds to red blood cells. I imagine that at least temporarily, it affects max oxygen uptake.
