be over the hill
To be past one's youth. Although often associated with age 40, this phrase is not tied to a specific age. Now that I'm over the hill, I'm sore for days after I work out. I'm not looking forward to my next birthday because I'll officially be over the hill.

over the hill, to be
To be past one’s prime. The analogy to a climber who has reached the top and is now descending has been transferred to the decline of aging since the mid-twentieth century, principally in America. Mary Roberts Rinehart used it in The Pool (1952): “The flawless skin goes, the lovely eyes fade, and she knows she is over the hill.” However, in U.S. military slang during World War II, going over the hill meant going AWOL (absent without leave).
