I used to get sick all the time when I was in school. And then when I moved out on my own and had a full time job (providing over the phone tech support) I was sick quite often. I’ve also had periods in my life when I would go years without getting sick, but then about a year ago I’ve started using sick days again.

All of the periods of time when I was getting sick coincide with me not wanting to go to the places I’ required to go (school, crappy workplaces, etc), and the periods of time when I wasn’t sick I was enjoying my job and the people I worked with.
