My immune system is about average, really. I don't get colds often, maybe about once a year. I do seem to get stomach bugs or food poisoning about once a year, as well - which is quite bad.
I have digestive problems (IBS), but that's a chronic illness rather than an immune issue.
I also have mild allergies to dust and tree pollen (which comes out in late April/May when the blossoms come, but is fine at the moment).
