Tidy health worker (7)
I believe the answer is:
orderly
This clue might be a double definition.
'tidy health' is the first definition.
'orderly' can be an answer for 'tidy' (I've seen this in another clue). I'm not sure about the 'health' bit.
'worker' is the second definition.
(I know that orderly is a type of soldier)
Can you help me to learn more?
(Other definitions for orderly that I've seen before include "Methodical, like soldier servant" , "Hospital attendant; well behaved" , "Systematically, not haphazard" , "Junior Army rank" , "Businesslike" .)
