Me, IF helps me to stop and think before I begin solving a problem.
(Counting how many cables of which colour and length I have in the overhead projector example.)
(And looking around the room to see if I have a chair or table nearby to stand on.)
(And checking the thing’s buttons.)
(I do not ,however, obsessively look around the room every 2 minutes.)
