What's awfully tiresome, I get older — time to enjoy life in France? (9,3)

I believe the answer is:

troisieme age

'time to enjoy life in france?' is the definition.
(French term for old age or retirement)

'what's awfully tiresome i get older' is the wordplay.
'what's awfully' indicates anagramming the letters.
'get older' becomes 'age' ('age' can be a synonym of 'get older').
'tiresome'+'i'='tiresomei'
'tiresomei' is an anagram of 'troisieme'.
'troisieme'+'age'='TROISIEME AGE'
