On: Everything with a battery should have an off switch

[lynx09]

What about pacemakers? If that is the exception, then not everything with a battery needs an off switch.

I had this same thought.

Also quartz wrist watches.

Turn that quartz watch into an automatic that you wear seldomly. (Aka you need to readjust the time each time you wear it!)
