Smoking

Three years ago today I stopped smoking. God I'm great. Here are the numbers:

12
Average number of cigarettes I used to smoke every day.

12 x 365 x 3 = 13,140
Number of cigarettes not smoked in the last three years.

100mm
Approximate length of one cigarette.

13,140 x 100mm = 1314m (nearly one mile)
Total length of cigarettes not smoked layed end to end.

Don't forget all the money that was saved, and subsequently wasted on other vices.
