Everybody in normal life (3)
I believe the answer is:
all
'everybody' is the definition.
(all people)
'in normal life' is the wordplay.
'in' indicates the answer is hidden within the clue.
'ALL' can be found hidden inside 'normal life'.
(Other definitions for all that I've seen before include "100%" , "SECOND PART OF 8" , "Every single one" , "Straight garden path" , "Total" .)
