How do you guys not stop to piss more!?!?!?! 
Lots of practice and A steel bladder

When you get older you gotta pee more. Heck.. nobody carries a pee cup or bottle these days?
We are older and yes I used to drive a 53 footer and when I hunt Montana by myself I have experience making truckers Tea, my go to is a 32oz Gatorade bottle!
