Can't you live without such statistics? (5)
I believe the answer is:
vital
'without such statistics?' is the definition.
I can't tell whether this defines the answer.
'can't you live' is the wordplay.
I cannot really understand how this works, but
'live' could be 'l' (electrical abbreviation) and 'l' is found in the answer.
The remaining letters 'vita' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for vital that I've seen before include "alive" , "Extremely important, essential to success" , "Of key importance" , "Characteristic of life" , "Imperative" .)
