If the drinking age of 21 is supposedly meant to protect brain development, isn’t the age of 25 really when the brain completes its development?

Question

This always annoys me. I’m told the drinking age is 21 because a persons brain continues to develop into their mid 20s, but at age 21, technically the brain is not yet fully developed so what’s behind the magic number of 21? Does it make it safer to drink at that age than at 18? Why isn’t the drinking age 25?

It’s about maturity. Which we still have a problem with. The existing DUI punishment system is too light-handed IMHO. It’s hardly a deterrent.
