My interesting post

the average human can hold their breath for 30-60 seconds. This limitation has more to do with the buildup of blood-acidifying carbon dioxide than the lack of oxygen, which your body stores in muscle proteins called myoglobin. People such as free-divers who practice diving underwater without scuba gear, have different techniques, such as hyperventilation, to decrease the concentration of carbon dioxide in the blood, allowing them to hold their breath for longer times. Denmark's Stig Severinsen currently holds the Guinness World Record for the longest free dive. In 2010, he held his breath underwater for 22 minutes.
