You REALLY need to educate yourself.
100+ million people with high blood pressure in this country. They are at a higher risk of complications including death.
23+ million people with diabetes in this country. They are at a higher risk too.
These are just 2 risk factors, there are more. But those 2 cover over a third of the population. So if you consider 33%
"a tiny percentage of the population", I dont know what to tell you other than to buy a fooking calculator.
They dont know everything this virus can do, and they are learning about it on a daily basis.
Educate yourself and speak facts instead of your opinion.
