Sandy, is Jim still smoking Cigs or is he using e-cigs now?
I smoked from the time I was 18 thru age 68 and am now vaping, just low nicotine...no tobacco. My brain's just fine, TYVM..

I do not have the type MS brain lesions that cause brain fog, either.
My brother died of prostate/colon cancer. He smoked all his life and his Doctor joked with him, that someone must have blown smoke up his Azz..
To much of any one thing can probably cause cancer....moderation in all things is the way I have tried to live and still am.
I hate fear mongering.

Stop looking down on me because I smoke/Vape!!!
