Why is it that some people seem to have a good immune, Ask an Expert

Academics

Why is it that some people seem to have a 'good' immune system (i.e., they never get sick), whereas others seem to catch every illness that comes along? Given what you have learned so far, which components of the immune system do you think can differ between individuals?
Why is it important for the acquired immune system to be divided into humoral and cellular immunity? Wouldn't it be easier to just have one of these branches? Why or why not?
