Some people are just not going to care or worry about it.
Talked to a WWII vet a few weeks ago. He's in his mid-90s, still in good health for his age, can still drive, and flat out said he is not going to worry about this virus. He fought in the Pacific and later in Korea and pretty much figures that at his age, anything out there could kill him so he is not going to spend what life he has left sitting at home waiting to die from some virus. If I was his age, I'd probably feel the same way.
My parents aren't nearly that old, but I do wish they would take it a little more seriously. Mom is completely oblivious because she thinks its all media hype, and dad is one of those people who never seems to worry about anything at all.
"If you will not fight for right when you can easily win without blood shed; if you will not fight when your victory is sure and not too costly; you may come to the moment when you will have to fight with all the odds against you and only a precarious chance of survival. There may even be a worse case. You may have to fight when there is no hope of victory, because it is better to perish than to live as slaves." - Sir Winston Churchill
