MOnica, yes we do make daily assessments of the risk posed to us but we all have a body of knowledge about safe road crossing, safe diving, smoking, over eating, alcohol use. We know much less about this virus as its early days.
In the first lock down, we wiped down shopping, changed and washed clothes if we ventured out. None of that now but I don't go into supermarkets, if everyone followed the guidance I'd feel less worried about shopping. Not everyone does. All it takes is some selfish idiot to sneeze all over the place and the virus is spreading. I've assessed that risk and ruled it out, for me. Sadly, my grandchildren are ruled out as well because they're in school and nursery and their parents working. Their risk is lower than mine so they can live their lives more fully than I can.
