Maybe it's better to say record time, but anyway this looks pretty related to everyone. Saying more than 20 minutes looks great and the record goes right now for 22.2 minutes. It has a little downside tough because the record was filling the lungs with pure oxygen and not conventional air.
Without it, the time should be cut by 10 minutes approximately and that continues in the greatness! It means that trained people could surpass that threshold under certain conditions.
Any person without specialized training should be near two minutes and after it the organism produces muscular movements that lead to the desired air intake for many, many functions.
