It cracks me up when somebody sez they never get sick.
It cracks me up & scares the crap out of me.
They say stupid things like .....
i never get sick!
iv not had the flu for years.
It's those people who's immune system is DEAD.
It's the people who never get sick who are the breeders.
New viruses evolve in these people as their immune system is not working.
It the same for humans as for computers, if you never update your anti-virus your system is vulnerable to infection.
So people who DO get the flu every 2-3 years or so are the healthier group.
As getting sick allows your body to update its anti-virus, thus making for a healthier overall system.
& people who get sick tend to have STRONGER immune systems,
( Their immune system fights the infection to the death )
