Ok so where are we going with all this? Is it ever going to become mandatory (not saying that it should) or are we all going to be persuaded with scientific evidence that wearing one is a waste of time or are we just going to carry on in the "I wear one", "I don't" camp? And are we going to carry on with these infantile comparisons with everyday life for ever?
It isn't, if I have anything to do with it. It's for those who want to impose the measure to demonstrate that it is desirable/necessary. I don't need to provide scientific evidence for what clothing I wear in my everyday life.
