The universe has a sick sense of humor. You stare at your code for 8 hours straight? Nothing. One lightbulb. But the second you step away to stuff your face, take a shower, or sit on the porcelain throne? BAM! Suddenly your brain floods with brilliant solutions!
It's like your subconscious is holding your debugging skills hostage until you're in the most inconvenient situation possible. And of course, the bathroom is where true genius strikes – probably because it's the only place where no one expects you to immediately jump back to your keyboard.
Next sprint planning I'm just going to schedule "tactical bathroom breaks" instead of debugging sessions. Much more efficient.
