1. We prefer to be safe, and shut the burner off while going to take a leak. It helps that we have a several thousand watt induction stove that boils pots of water in a few minutes, so there is no real need to parallelize boiling water with bathroom breaks.

We specifically want to prevent scenarios like: you take a leak, the leak turns into a shitting session or a phone call, you forgot you left the burner on.

2. Most of the time my wife and I make food together so if one person needs to take a leak the other one is around anyway.

3. For long slow cooking, we have plenty of comfy seating in the kitchen/dining area where we can get work done while being in sight of pots.

4. We have 2 pets we'd need to locate in an emergency, and so we tend to put electrical and fire safety higher than most people.
