Are they a consequence of original sin? I'm sorry but in my view 4 limbs is plenty for any lifeform - I mean snakes get away with none. So I go out for a pleasant walk in the countryside today and after a few hours of having the flies dive bomb my ear I was starting to feel like winter couldn't come soon enough, but then the final track back to the carpark seemed to be a mass breeding ground for some flying ant like creature and they are swarming all over me. The end result is as I try to swat frantically about my head to keep them out of my ears and eyes, my wedding ring goes flying off into the heather never to be found again. Bugger!
