Is salubrity somehow related to being famous?

You might be able to claim celebrity status for being salubrious . . . if you're promoting good health and wellness. Salubrity refers to heartiness, healthiness, wholeness, or a sense of vigor.

In David Coppperfield, Charles Dickens writes the following:

'Sir,' said Mr. Micawber, 'I rejoice to reply that they are, likewise, in the enjoyment of salubrity.'

James Joyce says in The American:

Decision, salubrity, jocosity, prosperity, seem to hover within his call; he is evidently a practical man, but the idea in his case, has undefined and mysterious boundaries, which invite the imagination to bestir itself on his behalf.
