Flatulence is a daily phenomenon. In fact, most human beings pass gas 10-20 times a day (yes, that includes you). Where does your bodily gas come from? Purna Kashyap takes us on a journey into the intestines, shedding light on how gas is made, which foods contribute most to its production...and why it stinks.
