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”
In the 2009 Korean film ‘Castaway on the Moon,’ a character states, “Desire makes humans smarter.” This reflects the protagonist’s ingenuity in creating useful tools from discarded items to survive on a deserted island. While knowledge enhances human understanding, it is desire that turns that knowledge into practical applications. Maslow was among the first to focus on this concept of desire in social science research. Understanding and addressing desires essentially means understanding humanity. - Joseph’s “just my thoughts”
