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 professions that people admire in the United States include police officers and firefighters. Another group of people is carpenters. A key concept in economic activity is “independence,” which means the ability to earn a living on my own.

I cannot leave my future in someone else’s hands. Poverty also implies that I am enslaved. - Joseph’s “just my thoughts”
