Teleport. You can control this by keeping some pepper in your back pocket. Id seriously be on some daredevilsht, jumping out of planes or robbing banks with a pepper packet up my nose.
You can kinda control farts, but there is often a 2hr delay that makes it useless. You also might not fart an entire 5 times after a trip to chipotle. God forbid you get food poisoning and wind up being 5 yrs younger in only just one day of being sick. Imagine how many sickdays you get per year.
Fun fact tho, the farting thing would actually make you immortal. Humans release all fluids and gasses after dying; meaning the last sound you make will probably be a fart.
