Risk factors for severe COVID-19 complications include obesity, cancer, diabetes, being over 65 years old, heart conditions, lung conditions, and kidney conditions.
42% of the US is obese. 5% have cancer or are cancer survivors. 10% have diabetes. 15% are over 65. Nearly half of American adults have cardiovascular disease. 11% have chronic lung disease. 11% have chronic kidney disease.
While there's overlap on much of these, some estimates put ~60% of the total US population as having risk factors for severe COVID-19 complications. 23% of the population are children. So we've got about 17% of the country who can actually work without high risk right now.
Not an argument in favor of shutdowns (I'm against shutdowns, mandates, etc.), but this "healthy people" concept is largely a myth. We are NOT a healthy nation. We're a nation primarily made up of sick and dying people who have failed to take care of themselves and are now paying the price.
So if we took care of ourselves we would live forever?
