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”
Living hard means saying when you are on the right track. Getting out of the way is the right answer if you've taken the wrong way. And you will live harder in the right way you choose again. Life is a choice before hard work. But most people try to win the choice with effort. In other words, this is called “hardship”. - Joseph’s “just my thoughts”
