Answer:
Metaphoric
Step-by-step explanation:
in the expression "living life to the fullest" you are not actually filling your life to the fullest with something. that would be weird.
What the expression is saying is that you need to spend every moment and every second living your life the way you want it to be, so that when you look back when your 50 you can say "yah that was me"
Hope this helps you!!!
