The magic immortal snail is the only thing that can kill you.

Very similar to the original immortal snail question, but inverse!

You are functionally immortal. Nothing can kill you. If you ever want to leave this mortal realm you must find and touch a single immortal unstoppable snail that is always moving away from you at normal snail speeds. You have no knowledge of where it is at any given time, only that it is actively moving away from you.

What is your plan?
