My dad was a long time cig smoker .... Marlboros. Sadly, they killed him age 66.
My grandfather (father's side) lived to age 76. Aunts said he'd only light one cig a day, that being the first one as soon as he got up in the morning, then simply used one to light another all day. In their house, there were always ashtrays at the kitchen table & "the adults" (IIRC) commonly smoked even during meals.
My other grandfather (mother's side) began smoking age 8. Told me he mostly smoked cigs then with whatever tobacco he & his buddies could scrounge, even harsh homegrown stuff. I think he also began smoking pipes at a young age. Worked for the telephone company, spent years up on telephone poles stringing wire. Told me he smoked Bugle tobacco, those little bags with a drawstring, and could roll his own cigs with one hand while hanging on to the poles. He gave up the cigs in his 50's (heart problems) but kept smoking a pipe. Had smoked many different types of pipes (always Billiards until he switched to Canadians) & in his younger years smoked various tobaccos, including his interesting story about trying pure perique. But what I remember, for many years, was that he only smoked Edgeworth Ready Rubbed, both in the pouches & the cans. Said he couldn't smoke aros because he inhaled, a carryover from many years of cig smoking. He ordered 7 new pipes (Dr Grabow or Yello-bole or John Rolfe) every New Year. Had a rack for a 7-day rotation. Smoked (example) his Monday pipe all day, many bowls, then it went into the rack until the following Monday to "dry out". Upon receiving his new shipment of pipes each January, the last year's pipes (which he claimed were "all burnt out", which I don't really believe because he took such good care of his pipes) were then "consigned" to his coal burning stove in his garage, right next to his workbench. Seemed to me like a fitting end to those pipes, although I wish I now had them. My sentiment & nostalgia for our friendship .... our thousands of games of Checkers, always with his pipe going .... carries on today with my pipe racks holding 5 wonderful Canadians .... my "tribute" to him.
