Hold your breath
Try holding your breath. After a minute you will have used up most of the oxygen stored in your body and carbon dioxide will build up, triggering senses in your diaphragm to start breathing. You will experience an overwhelming urge to gulp some air, something which you will not be able to resist.
On average, people can hold their breath for one minute, maybe two. The world record, however, is 11 minutes 35 seconds, set on June 8, 2009 by Stéphane Mifsud. In that time, even if you held your breath for a minute, you would have had to breathe 170 times because you breath 23,000 times a day!
