//Wouldn't we have to prove our 'medical' condition for not wearing a mask? If not, we could all claim to be claustrophobic or asthmatic or whatever.//
No ken. In fact only two of the seven on the (non-exhaustive) list of reasonable excuses are medical related.
//Can't really get my head round people that are calling other people paranoid about this virus, are they not just being careful, may be its you that's paranoid DD with forecasting the latest odds?//
Well, teacake, you can be careful. But you have to weigh up the risks against the costs. The risks are extremely low as DD has pointed out. Would you, for example risk a sizeable some of money on something that had a 4000-1 chance of success? The costs of hindering further an already crippled economy are enormous.
//DD is trying to express how much braver he /she is compared to other folk, and he/she has got a better grasp of the situation than anyone else on the planet.//
It’s nothing to do with bravery. It’s simply weighing up the risks and the costs and making a reasoned decision. Not everybody on the planet (or even in the UK) is of the same mind. I subscribe to a number of forums and one in particular is virtually 100% in line with my thinking. The country needs to get a grip and understand that going out is not fatal, passing close by another person is not dangerous and handling something that somebody else has touched is quite normal.
