Here's what your Wordiq has, WW:
From WordNet 2.0 :
Spry : adj : moving quickly and lightly; "sleek and agile as a gymnast"; "as nimble as a deer"; "nimble fingers"; "quick of foot"; "the old dog was so spry it was halfway up the stairs before we could stop it" [syn: agile, nimble, quick]
I too have it in my mind as something I would say about an older person.
jheem--looking forward to your tales of the lost words.
