It's a weak virus. It only seriously affects those that had serious health problems to begin with. I've looked at the data before, something like >90% of those killed are >65 years of age.
Those under 65 that are killed are either morbidly obese or were only alive in the first place because of other medications and treatments barely keeping them breathing.
Amazing country to live in, where majority of the population stuffs their faces with junk "food" all day, every day, until they are 85% body fat; taking up a ridiculous amount of space, increasing health insurance costs for everyone else, demanding special treatment everywhere in public (ex: foot traffic through an entrance/exit must come to a standstill because a 450 lb hippotamus who is only 30 years old is wider than three people and can't waddle more than a fraction of one mph. But hey, they're wearing their mask, so they're doing their part to contribute to a healthy society!) and then they blame people who actually live healthy lifestyles for all their problems.
