Inhalant allergies from dust and pollen, seasonal ones from dust and pollen, and maybe constant ones from danders on cats and dogs and chickens and feathers and your pillows and that kind of thing, maybe even chemicals that come out of rugs, and new cars, like formaldehyde and other chemicals, you want to get your immune system working optimally so it can protect you from these things.  Because most people are able to tolerate them.  And what happens is when your immune system doesn’t have enough nutrition to function optimally you become a victim of these things assaulting you all the time.
