I assume those were years in which he was 11, 12, and 13?
An implied floor(age) hadn’t occured to me. I suppose that means that on average the 14 year olds in question would have 0.5 years in which to become a regular smoker. An… interesting… thing to measure. The ones that would be most likely to be smokers would then be those that are closer to 15 than 14.
