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”
The essence of cubism is to get rid of the viewpoints of the object. Cubism shows us the inside and outside, top and bottom, front and back of the object simultaneously with 2D reorientation, as a result, the observer's viewpoints disappear altogether. Finally, cubism makes us see the whole of the object. If you want to see the real world, throw away your viewpoints completely. - Joseph's "just my thoughts"
