I am declined
Into the vale of years. [ William Shakespeare ]

Greatness, once fallen out with fortune,
Must fall out with men too; what the declined is,
He shall as soon read in the eyes of others
As feel in his own fall. [ William Shakespeare, Troilus and Cressida ]

Life sues the young like a new acquaintance.... To us, who are declined in years, life appears like an old friend. [ Goldsmith ]

The Greeks adored their gods by the simple compliment of kissing their hands; and the Romans were treated as atheists if they would not perform the same act when they entered a temple. This custom, however, as a religious ceremony declined with paganism, but was continued as a salutation by inferiors to their superiors, or as a token of esteem among friends. [ Disraeli ]
