Virtually no one starts smoking after age 26

There's a reason the government has had to severely restrict cigarette advertising (and smoking in general) to minors: they're the only ones still gullible enough to think smoking is a good idea. According to the Surgeon General's office, anyone over the age of 26 has a better chance of being mugged by a great white shark in the dark alleys of a central European hamlet than they do getting hooked on nicotine.
