Fair enough ... but having a whackload of people in hospital with COVID putting a strain on other illnesses and emergencies is not desirable, is it? Here's a nice link giving hospitalizations per million for Canada, the US and the UK. You can add and subtract as you wish. UK has not reported any data in the last while. Canada has a relatively high number at the moment. Is it an unwanted strain of the health system?
Your Grandad sadly was taking up room that might have saved somebody else's (non-COVID related) life.
Again, it's not about you or even your Grandad, it's about the system/community.
