Did You Know? The average mammal takes 21 seconds to empty its bladder.

No one will blame you if you’ve never bothered to time yourself on the toilet. But you may be interested to know that researchers from the Georgia Institute of Technology found that most mammals weighing more than six pounds take 21 seconds to pee. According to Live Science, this oddly consistent time is due to the fact that the urethra is “appropriately scaled” to be a “flow-enhancing device.” And apparently, the perfectly enhanced flow takes 21 seconds to complete.
