Person tending to be bored by the mid-point of their working life (6)
I believe the answer is:
career
'working life' is the definition.
(I've seen this before)
'person tending to be bored by the mid-point of' is the wordplay.
I cannot really understand how this works, but
'tending' could be 'care' (synonyms) and 'care' is found in the answer.
'point' could be 'e' (compass point) and 'e' is found in the answer.
A single letter 'r' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...
'their' is the link.
Can you help me to learn more?
(Other definitions for career that I've seen before include "Mad rush" , "Work history" , "One's business path through life" , "course securing professional employment" , "Move headlong at high speed" .)
