Hairy moments

It feels like evey time I go into the Overwater office at the moment someone has either grown and beard or shaved it off – I just can't keep up! First it was Colin who kept his Movember beard then arrived back after holidays completely clean shaven (I just couldn't put my finger in what was so different about him), and now Sam's going for it with a re-growth! Only Dave has refused to be drawn in to all the hairy mayhem. Anyway all this hairiness has left me pondering......I wonder if people who have outdoors jobs, or activities (narrowboating could be a good one) evolve to be hairier to keep warm?? Could that explain the high percentage of beards in the marina? I'll leave you to think about that one....
