Take your time, for instance, producing biography rotating regular breaks in the afternoon
I believe the answer is:
life span
'breaks in the afternoon' is the definition.
The definition suggests a singular noun which matches the answer.
'take your time for instance producing biography rotating regular' is the wordplay.
I cannot really understand how this works, but
'biography' could be 'life' ('life' can be a synonym of 'biography') and 'life' is found in the answer.
The remaining letters 'span' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for life span that I've seen before include "Length of existence" , "Period of existence" , "Duration" , "From birth to death" .)
