Places to drink to one's health (4)
I believe the answer is:
spas
'places' is the definition.
The definition and answer can be both locations as well as being plural nouns.
Maybe you can see a link between them that I can't see?
'drink to one's health' is the wordplay.
I cannot quite understand how this works, but
'one's' could be 'as' (a thing is one thing) and 'as' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
'to' is the link.
Can you help me to learn more?
(Other definitions for spas that I've seen before include "Health resorts near springs" , "Mineral springs" , "Bath and suchlike" .)
