I'm short of 70 by a few years as well. My concern is for the very healthy over 70s out there who will be almost complete shut ins. I've been in agreement with the government until now with their policies of handling the virus, but this is overkill. You leave it to the bureaucrats long enough and they will eventually **** things up.
There are people over 70 who are in better shape than people many, many years younger. And even if they aren't in the best shape it is their right to have the same freedom as anyone else. This is worse than fascism.
