Years of Age

Ok, so is it just me? I’ve googled and not found anyone else asking about this.

Whenever the Olympics come around and they start talking about individual athletes, how come they never say, “She is 25, and this is her first appearance?” How come they never say, “She is 25 years old, and this is her first appearance?

They always say “She is 25 YEARS OF AGE!”

Sheeesh!!! What about “pounds (or kilos) of weight” or “feet (or inches, or cm) of height?

What is up with that???
