'...don’t you care if you are possibly infected?’
No.
I cannot spend my life wondering whether I have a virus or not. If I feel unwell I'll seek medical treatment (if it's sufficiently severe to warrant it). If I don't, I won't. In any case, I doubt I'll get any because the primary healthcare service where I live has all but ground to a halt, but that's another - albeit related - argument.
I've had my two jabs and almost everybody else who wants them should have had them by now. That's all I'm prepared to do because no matter what measures are imposed (short of locking everybody inside their homes 24/7 for the foreseeable future - and even that won't work because there will be people out on the street imposing the lock in) this virus will spread.
It is now apparent that measures to contain the virus have taken a huge toll on the (non-Covid) health of the nation, almost certainly far in excess of any damage caused by the virus. That's not to mention the economic damage that continues to accumulate. It's time to stop.
