An immune system is a collection of mechanisms within an organism that protects against infection by identifying and killing pathogens and tumor cells.

I'd like to know how many times in a year do u fall ill. By Illness 'I mean fever, flu, diarrhea, or any other physical illness that'd require rest.

What interests me is how some ppl amazingly get sick more often than others who rarely get sick. I'd like to see the ratio.
