Definitions (Wiktionary)
verb
to degenerate; to atrophy (syn.) 老化
verb
to deteriorate; to worsen; to decline; to fall; to drop
The young are not our inferiors. Old people have more experience, which of course is a strong point, but on the other hand their physical powers are declining, their eyesight and hearing are not so sharp as before and their limbs not so agile as those of the young. This is a law of nature.
