'went to bed' is the definition.
('retire' can be a synonym of 'go to bed')

'weary again' is the wordplay.
'weary' becomes 'retire' (retiring is a kind of wearying).
'again' becomes 'd' (I can't justify this - if you can you should give a lot more credence to this answer).
'retire'+'d'='RETIRED'

'being' acts as a link.

Can you help me to learn more?

(Other definitions for retired that I've seen before include "Pensioned off" , "Left" , "went back" , "No longer active in work or profession" , "Stopped working" .)
