Traditional IRA Withdrawal Rules With a Traditional, Rollover, SEP, or SIMPLE IRA, you make contributions on a pre-tax basis (if your income is under a certain level) and pay no taxes until you withdraw money. IRA withdrawal rules and penalty details vary depending on your age.
LPG (propane) smells because an odourant - Ethyl Mercaptan - is added to the gas to make it easier to detect a leak. In their natural state, LPG (Propane and Butane) and Natural Gas (Methane) are all odourless gases. The distinctive smell that people associate with these gases is actually added to them as a safety measure.
All of these gases in the digestive system have to escape somehow, so they come out as farts! Gases are also what can make farts smell bad. Tiny amounts of hydrogen, carbon dioxide, and methane combine with hydrogen sulfide (say: SUHL-fyde) and ammonia (say: uh-MOW-nyuh) in the large intestine to give gas its smell.
