Extreme cold a friend who smoked had his ritual, you know the one, where you get out the pack and smack it down a few times, get out a cig, flick the bits off the filter, and smooth it all and replace the pack before lighting it.

In cold weather he would start his little ritual by placing his lighter under his arm beneath his coat. By the time he got to the point he was ready to touch flame to it the lighter was warmed up and ready to go.

I thought all smokers knew that one.
