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”
Expertise is not “to know only me,” but “to make understanding others to know with what only I know for.” It is not expertise if I cannot persuade others by overwhelming them with my things. The expertise that failed to convince and communicate is called “stubbornness”. “Collective intelligence” is the expertise that succeeds in persuasion and communication, and does not mean a stubbornness that enforces consensus. - Joseph’s “just my thoughts”
