The process of ossification and bone growth won’t stop until early adulthood — usually around the age of 25. At this point, you’ll have 206 bones that are as big as they will ever be.

However, through a process called remodeling, bones will form new bone tissue and break down older bone into calcium and other minerals to be released into the bloodstream. That part of the process is called resorption.

And if you really want your mind to be blown : Your skeleton completely regenerates itself every decade or so through remodeling.
