I have plenty of opportunity to do so, I work as a shipbuilder.
my work takes place primarily in the very beginning parts of module construction, lots of welding, grinding, burning, etc. Many people chain smoke cigarettes as they work, and I could get away with clenching a pipe in my teeth and tools in my hands... However, one of the things that I value about pipe smoking is that it doesn't lead to "fiending" so I tend to wait until I arrive home and can really enjoy it. Although having a pipe for when I am consulting a drawing or filling out paperwork would be rather nice. hmmmm...
