I can't blame you for thinking this way at all. However the reality is that it's not so much a clean subtraction where you lose X amount of time at the end of the tally,but rather a gradual decline where bad habits end up harming the quality of your prime "temporal real estate" even if the actual last gasp comes much later. That's why to me a Coke is also a poor investment in the present, all things considered. Not to mention that the craving for one is quite situational.
