i got liquid in my lungs from pheumonia had this shit last year. i wonder what caused it this time. last year i didnt get a flu shot. and i went out in the rain and stayed out 4 12 hours stupidly. but this year i got a shot and stayed out of the rain. it could be something in my house. colds are easy. flus a bitch. but this shit knocks u down hard. anyways take care dude
