'obviously not new-laid' is the definition.
I can't tell whether this defines the answer.

'an egg i scrambled' is the wordplay.
'scrambled' is an anagram indicator.
'an'+'egg'+'i'='aneggi'
'aneggi' is an anagram of 'AGEING'.

Can you help me to learn more?

(Other definitions for ageing that I've seen before include "getting more advanced?" , "Growing old" , "rather old" , "Declining" , "process of development" .)

I've seen this clue in The Globe and Mail.
