Can I say "in age only"? [closed]

Does this phrase work?

"A senior in age only, he's never lost his strength."

It is meant to be a variation of "by name only", although I can't seem to find it used. Will this work, or does it sound off?


Solution 1:

It's an expression easy to understand even if you've never heard it before. Plus, I found some examples:

  • Bichon frise Buddy's a senior in age only — OC Register

  • At this Party, a Generation Gap in Age Only — Hartford Courant

  • Pitcher a freshman in age only — SM Daily Journal
