Fat people and elderly (mainly confined to nursing homes). What do these two groups have in common? They don't move. They sit or lie around all day. Not all fat people, but many of them are fat because they have a habit of sitting on the couch and lying in bed without exercising their lungs at all. This gives the virus the perfect opportunity to survive. If you don't believe me, just factor in one of the treatments the health providers have been using instead of ventilators. I can't recall the medical term, but basically, they roll patients over on their stomachs. Just that little bit of movement helps their lungs clear up. If a fatass with covid would get up and walk around the block a couple times a day, they would survive just as easily as the rest of us. It's not fat or old age that is allowing the virus to kill them. It's lack of exercise. If you get the wuflu, don't lie around in bed waiting to get better. Get up and move around. This is why young kids don't die. They are full of energy and can't stay sitting or in bed all day.
