Thank you. I am so sick of these medically-illiterate idiots spreading their disinformation. Plenty of young, healthy, athletic adults -- and many children as well -- have died from this disease so far. There are obvious genetic components that we don't understand yet. Why does one partner in a couple die, while the other does not? Why does one elderly person in a nursing home make it, while others do not? Why does a perfectly healthy new baby die from it, while his grandparents do not?
Stretch might as well blame cancer patients for their disease. "Should have taken more garlic! Should have eaten your veggies! Should have been lucky like me!"
A person can be young and outwardly healthy and have a weak immune system.
