Worry about race (4)

I believe the answer is:

care

'worry' is the definition.
(eg without a care means without a worry)

'about race' is the wordplay.
'about' indicates anagramming the letters.
'race' with letters rearranged gives 'CARE'.

(Other definitions for care that I've seen before include "Protective custody" , "Caution; keeping" , "Have concern or regard" , "Mind" , "Attention - caution U protection" .)

I've seen this clue in The Mirror.
