not help you fight it off once you have it. I know for a lot of the population you are sick for a little while then are fine. For those that get really sick it is devastating. And no way to tell who will get really sick.
There is a really easy way to tell who will get really sick. Old people and people who are diabetic fat immunocompromised and or have COPD. Also you should not tell people you are a doctor when proffering your opinions unless you are going to display your license. Anyone can put MD in their user name. I guess it makes you more authoritative when you spout what you think which is really no better than what anyone else thinks. My mother went around telling people she was a Supreme Court justice but she was just mentally ill.
