the number one rule in diving is to never hold your breath. My (stupid) question is: if you had to how long do you think you could hold it" I know once in held mine for 3 minutes in a swimming pool, but that was being completely motionless and relaxed.
Also, whenever I concentrate on something, like trying to thread a needle, I hold my breath. I have to be very conscious of this when diving.
