Research has found that your life is already over.

Many people say they feel they've made their best memories by the time they hit 30 or 40... but a new survey finds the age is actually closer to 25.

The survey took what the researchers called a "naturalistic approach" and asked retired people to tell free-flowing stories narrating their own biographies in just 30 minutes.

They say their findings indicate a lifetime's "best moments" are etched on the brains of most people by the mid 20s.

The so-called "reminiscence bump" mostly happens between 17 and 24, when most people describe parts of their lives as beginning and ending.
