Diving into the water without an oxygen tank is called ‘free-diving.’ It is a form of apnea diving in which divers must hold their breath for an extended period while diving deep into the water with just one breath of oxygen. The difficulty in holding the diver’s breath during this time is not due to a lack of oxygen but rather an increase in carbon dioxide concentration. In other words, if you keep your heart rate low and your metabolism slow, you produce less carbon dioxide, which allows you to dive for a longer duration. The only way to maintain a low heart rate is to remain as calm as possible. Maintaining calmness has numerous benefits in life. - Joseph’s “just my thoughts”
Human behavior and psychology are tricky and complex. If you ask someone who prefers short-term gains, “Would you like to get $1,000 now or $1,020 a year from now,” the person will choose the former. However, if you change the question, “Would you like to get $1,000 in 10 years or $1,020 in 11 years,” people will choose the latter. The taking of time and possessiveness are even under the same conditions, they make different choices. These two dominate the human personality. - Joseph’s “just my thoughts”
