00:00 If your friends think you go to the bathroom too often, well, keep going.
00:02 Because holding back a craving has psychological effects on your brain.
00:05 That's what a study found in which volunteers were made to drink water,
00:09 they were prevented from urinating, and they were made to do different tests all along.
00:12 And they found that having a full bladder has the same impact on our decisions
00:16 as if we were drunk or hadn't slept for 24 hours.
00:19 So go! Don't hold back, whatever they say.
