I don't get it. Does someone have the science as to how it's more dangerous to be in a yoga class, on your mat, 2m from someone else, than on a treadmill, and then a rowing machine, and then a stepper than several other people have used before you? Why is my son's swimming class allowed to reopen but not my daughter's gymnastics? I get that it's outdoors, but having thousands of people in a stadium, presumably using the same loos and corridors to watch a match, why is that okay but not a dance class of a dozen people in their own space?
