Is it okay to cough into my shirt?
Today in school somebody was mad at me because I have a cold and I have a habit of coughing into my shirt--pulling at the collar and coughing onto my body straight down through my shirt. He said that it goes through the shirt enough that it would affect him (he sits about 4-5 feet in front of me.) His reasoning, at least, was wrong--he said that mythbusters showed that coughing goes through a handkerchief, which is thicker than my hand. (I looked up the video--it really shows that SNEEZING into a handkerchief is a bad idea because it gets on your hands, not because it goes into the air.) But still, is he right?
