Easy for you to say when you aren't the one on the front line (I'm blindly assuming you aren't in health care). You have no idea what the health conditions of him or his family are. If they have high blood pressure, diabetes, or any other underlying health condition, that can exacerbate their risk for the more severe symptoms.
2 nurses, aged in their 30s, died in the UK from COVID. One doctor in China died at the age of 35. Another doctor, aged 51, died in Italy.
These aren't old folk.
As I said before: I am working with the children of those who are, with no kind of protection available to us. And even then it would be reasonable for me to stay home because I belong in the highest risk group available (cardio-diseases) yet I still work because I do not have a choice. (I could stay home, but who'd babysit the children so that the parents can keep the system running?)
We are a team of 3 people, one is sick, one has to care for her elderly father and just lost her mother.
And as I said: He'd mention the age but forget to mention relevant diseases? I do not think so.
What you have to consider is, thag not every person who is more at risk (men than woman, age etc.) means they should be instantly putten off duty. Then every person who ever had a cigarette in their hand must be excluded. Obesity was mentioned before, isnt the rate about 30-35% among Americas population? Who do you think will be left in the hospitals if you exclude one after another from duty? You cant exclude every risk, especially because we do not know what exactly puts us at risk.
Diabetes, cardio diseases (not 'high blood pressure from anger' kind), asthma...these are serious conditions.
30 year olds die. Yes. The chance for that is low. 0.2%. That still means it is possible that they die. Nobody (except <10 year olds) are safe. Everyone is at risk, older ones (50+) are at higher risk. So are sick/people who suffer from health issues such as myself.
So that means it is saver to send 40/30 year olds into hospitals than 50(1,3%)/60(3,6%) year olds.
In the end 60% of the population must have contradicted it and survived it to build up herd immunity. So its very likely that if you are not in the risk group, you will get it either way. There is no other way to reach 60% rate.
