I've had pneumonia 29 times an I don't know why. Reddit ask me anything

Let me elaborate for everyone so you have a better picture. When I was of the ages from 2-5 I had pneumonia approximately 8 times. From that ages of 6-8 or 9 I had Maybe 1 or 2 at the most. Ever since then I have caught it 1-2 a year and im 16 currently.

IF ANYONE HAS IDEAS ON HOW TO KEEP MYSELF AS HEALTHY AS POSSIBLE THEN PLEASE LET ME KNOW. I AM LEGITIMATELY SCARED FOR MY LIFE.

Thanks to everyone who reply to my post
