As mentioned, it's a delusion. Muscular and skeletal portions of the body are less impacted. But if you could see their naked bodies (no homo....just medical peek) in contrast to most men same age who are non-tobacco users you would likely be astonished at the difference in skin condition. It will be drier, any and all cuts will be more scabbed and/or unhealed lesions. The insides of their mouth will be frankly in a decomposing state and most of their internal organs will be smaller than those within non-tobacco users due to decades of inadequate healthy cellular reproduction.
well i haven't smoked since harry started this thread so maybe we can all quit together
