Breaking the seal

In my first ever blog entry, I'll introduce the concept. You ask us a wild question, we'll try and answer it. Every Saturday we'll choose the best question submitted, work on it throughout the week and post our Bestimate 7 days later.
We'll post our methods, research, calculations and try and answer any queries.

We're going to start with a question asked last night in the Pipeline bar. Mr Patrick McCarthy asks;
"If you join together all of the cigarettes smoked by a smoker of 20 years, how long would that cigarette be?"

A wild question indeed, Bestimate next Saturday. X
