Salubrious Continuation

Salubrious means wholesome, healthful, beneficial. Maybe that's why we say, Salute! To your health! Yes, both are from the same Latin root.

Continuation means state of or act of continuing, progressing. It comes from the verb continue, which means to exist over a long period of time, to last, to carry forward, to persist, from Latin.

I'm looking for a better term for aging. And for old. Why do we say, How old are you? In other languages they say, how many years do you have? We could say that, too!
