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 animation “ Finding Nemo ,” the main character, Nemo , asks questions about the sea and where he lives. “What is the sea?” Hearing this, the dolphin puts Nemo on its back and jumps over the water to reveal her world. When you are in the sea, you do not know what the sea is. However, when you rise above the surface, you can see that the sea is a place where water gathers at a low level, and above it are air and land. She eventually realizes that she is also on the ground with water. If you want to understand the essence and grasp the reality, you must step out of the place you belong to for a while. Further development and reform can be expected. - Joseph’s “just my thoughts”
