at the age of vs aged


New Member
Hello, members of the forum :)

I'm a little confused by the usage of the constructions "at the age of" and "aged". Can we say that in some cases they can be used interchangeable? For example, do both of them sound fine in this example:
"Citizens aged/at the age of 18 and older must contact the director"?
Thanks in advance!
P.S. If I have any mistakes in my question, please, point them out

    "At the age of..." indicates a point in that person's life, so you can't add "and above":

    He climbed Mount Everest for the last time at the age of 76.
