My dad smoked Kools - for most of his cigarette-smoking career, which ran
from age 13 to age 75.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I started at 13 also, quit after 50 years at age 63. I’m 78 now and breathing just fine. Doc appointment just yesterday, oxygen level 99.

I smoked for 21 years - and quit at age 42.
I'm breathing fine also. Now I am.
But one late May morning I started coughing, and coughing - I couldn't stop coughing.

So I figured that I had to make a decision to either stop smoking - or stop breathing.
I made the smarter decision, obviously.

PS: I'm 59 now.

And my oxygen level was 99 yesterday also.
Seems like it's almost always 99.
Except when I do a heavy workout - then it might drop 1 or 2 percentage points.
