It's an old joke, but relevant to the discussion: Woman: Do you drink beer? Man: Yes Woman: How many beers a day? Man: Usually about 3 Woman: How much do you pay per beer? Man: $5.00, including tip Woman: And how long have you been drinking? Man: About 20 years, I suppose. Woman: So a beer costs $5 and you have 3 beers a day, which puts your spending each month at $450, or $5400 annually. Not accounting for inflation, you have spent $108,000 in the last 20 years! That money could've been put into an investment account and, after accounting for compound interest for the past 20 years, you would now have enough money to buy a Ferrari. Man: Do you drink beer? Woman: No Man: Where’s your Ferrari?
