Hahah, well, who knows , every penny counts. When I was a kid, I had a friend that who's father smoked heavily, like 10 packs a day, and for over 30 years. We did a calculation and calculated that he has spent so much on cigarettes, that he could have had enough money to buy a house if he had deposited that money in a bank with those interest rates back then. Because they were living in rent, they lost an opportunity to buy a house.

It is pretty sad that humans live very inefficient lives, not to mention unhealthy. Money just passes by most people.
