I found the following advertisement in my Bank’s Investment Magazine.
Basically, what it says is that if you stop smoking and save the money, in 10 years you can buy a motorcycle, in 20 years a car, and in 30 years a boat.

You would save 2.9EUR/day and invest the money. They use an annual interest of 7.25%. The reference price for the bike is 15k EUR, for the car 47k EUR and for the boat 112k EUR.

Stop smoking and start saving… :-)
