Rarely. I caught two colds back to back at the end of 2012 and again last Januray. Before that, I hadn't been sick for about 3 years. I think it was because I started a new job and started taking the city bus to get to work.

I have too many days off from school with headaches, fatigue and sore throats, although sometimes it's self inflicted.

I haven't been physically sick in over 5 years ago, so I never get the serious stuff.

maybe a few times a year,if that.

When i was younger i used to get sick almost every year with a cold. Sometimes twice a year.

Nowadays its a rare occurance. I dont think i have been sick for almost two years now. Well, not with the common flu. I dont have allergies. I do have one annoying genetic disease, but its nothing that impairs my everyday life. It just makes me take longer after the shower (need to pass some cream on some areas).

Besides headaches, I just get sick once a year. I get 1 cold early in the Winter that intermittently lasts until early Summer

at some point me getting sick was very rare,either once or never in a whole year, then at junior high i started getting sick like once per month/2, which added to the natural depression teens get at that time.
now i get sick about once per 5-9 months on average, not as good as i once was, but a lot better than my JH years.

Not a lot but I remember I got sick multiple times in my graduation trip. The nurse at the hotel was really hot! She suc-- I mean cured all my pains.

I don't have no allergies at all, flue maybe once every 2 years.

Maybe once or twice a year if that. But annoyingly i have had exma on my hands for the last few years, it's get especially bad if i'm stressed or there is very cold weather. But goes completely in the summer time

No more than twice a year, if even that often.
My immune system kicks ass.
