Just to be clear
You cannot OWN YOUR OWN RISK
Too many people get involved if things go wrong.
You can OWN YOUR OWN personal SCIENCE though, to keep you out of trouble
So if you think you can get through co-vid by taking on the risk all to your self , think again.
Better still, science there again with fresh ideas.
BTW There is no such thing as zero risk. It is debatable whether there is any such thing as zero science within any Human.
