I had a great uncle who was a Catholic Priest.
He picked up the habit of chewing tobacco while serving in a mission overseas. He chewed the rest of his adult life.
When he passed away at age 94, the State of New York listed “tobacco use” as a contributing cause of death on his Death Certificate.
Gotta have the statistic, dontcha know.
My grandfather enjoyed his Scotch. Not to excess, he just liked a scotch or two in the evening.
Many, many years ago, his doc told him to quit drinking. Grandpa's response? He fired the doc, on the spot. "What did he think it would do, stunt my growth?", he said, approximately.
Grandpa lived to the ripe old age of 87, and enjoyed his scotch more-or-less right up to the end. :-)
