Okay kiddo, so sometimes when someone does a really bad thing, they might be told they can't do certain things anymore. This is called an order.
A lifelong restriction is when someone is told they can never do something for the rest of their life. For example, they might be told they can never go near a certain person or place ever again.
This is usually done to protect other people and make sure everyone stays safe. It's very serious and means the person has to follow the order forever, even when they are very old.
It's like a rule that they have to remember and obey forever and ever.
