man flourishes with age
Proverb meaning that one should grow more vigorous and active as one gets older, rather than decline.
My grandfather says, 'Man flourishes with age,' and continues jogging every morning.
Mixed kanji-kana form; the adverb ますます is written in kana.
Based on the Classical Chinese maxim 老当益壮, “one should become still more vigorous in old age,” associated with the general 馬援 in the 後漢書.
