From my observations, having travelled in recent days on Tube, train and bus, it is to quite a large extent a generational thing. Most mask-wearers tend to be 35-40+; most mask-deniers are in the younger bracket. Hard to give specific proportions, but I was left in little doubt that the younger a traveller is, the more likely that he/she will ignore the official advice. Anyone else got input?
