So I wanted to challenge myself on this one, I had a gallon jug of water & a timer. I set it for 1 hour to finish as much as I could, I drank about 3/4 of the gallon in the hour. I then set another timer for 1 hour that I couldn’t go pee til it went off. A light urge hit me at about 45 mins in so I ended up chugging the rest of the gallon while waiting for the urge to get worse. The timer went off & I was still holding it no problem so I set another 30 min one & the urge started to get stronger towards the end but I will say I could of probably held it for another hour if I wanted too. That is what you call a bladder of steel! I hope you all enjoy this video :)
