There's nothing that says everyone under 40 will be fine. Even if it doesn't put you in the ICU it could damage lungs or organs. Kids can kill any elder 50 to 90 they come in to contact with including family.
You're complacent. You will be the one coughing all over food in a grocery store. You're more dangerous than the virus itself.
I'm not complacent and the fear will cause more damage than this virus.
