in the 1950s, as a smart-alec kid, I did some rapid arithmetic and informed my parents that if they had not somked, and had saved the money, they could buy a new Cadillac. (based on about 25¢ a pack and 5000-7000 for a Cadillac)

They were NOT amused.....

But, since health is far more important than cars, I applaud your efforts, Dan
