There is generally no harm in smelling smelly farts on a regular basis. Fart is the human body to digest food process, food after digestion and fermentation and decomposition, but also generate a lot of gas. The main components of these gases are nitrogen, hydrogen, methane, ammonia and so on, so it will be accompanied by some flavor. Usually, the amount of farting at one time is not very large, and it spreads with the air very quickly, so it is possible that people who are sensitive to the smell will soon notice it. As long as you do not inhale a large number of farts in a short period of time in a closed environment, there is generally no harm in smelling farts on a regular basis. If discomfort occurs, it is recommended to go to an open place with plenty of air and take a deep breath to relieve the discomfort. If the situation is more serious, it is recommended to consult a doctor for reasonable and standardized treatment.
