Up to Pee? Normal.
40 Minutes Awake? Abnormal.
At 65, your bladder is supposed to wake you once, maybe twice a night. That's physiology and not the problem.
The problem is what happens next: you lie back down, your brain turns on, and the clock crawls from 3:17 to 3:54.
Ten years ago: same bladder, same hallway, same cold floor, that trip cost you no time.
The only difference is the depth of your sleep.
