Hey! Ever since I was a kid, I had a lot of problems with my respiratory system. When I was really small, I had bronchitis. Later on, I developed pneumonia when I was seven years old. Since then, I had it once when I was a sophomore in high school, twice in the senior year and yet again as a freshman at a uni (currently). I am 19 years old and I was wondering if anyone can help me find out how to boost my immunity to pneumonia. I eat relatively healthy, although this varies at times. I am a vegetarian and I sometimes eat/drink excessive dairy products.
