I am not sick. I am not around sick people. I live in an area with virtually zero infected people. Masks are not required anywhere I travel. Not in any stores and not in any public places. I cant spread the disease because I don't have it. I cant catch the disease because no one around me has it. Im not vulnerable to the CV if I do catch it.
As you mentioned, old vulnerable people are the most at risk and often the people who aren't wearing masks. Do they even care about their health at all? Why are they even out in public? Why aren't they in full lockdown and quarantined? Everything they need is available via on line ordering and delivery through family, friends or senior services. The old and vulnerable are the people at risk. They, along with their families should be taking precautions.
