Suspended Animation is the act of stopping or slowing down the vital functions of an organism for a period of time, especially by freezing. Your insurance covers this function for your character when you are away. Pushing this button will initiate the logout procedure. You cannot be in combat and need to be sitting for the logout procedure to start.

Once the logout procedure has started, you can end it by clicking this button. That will tell your insurance system that you do not wish to enter Suspended Animation this time. You have to press this button within 20-30 seconds after initiating Suspended Animation to cancel the request.
