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”
Wine contains "polyphenols," which are antioxidants, but it also includes ethyl alcohol, which is a Class 1 carcinogen according to the World Health Organization. Wine sellers emphasize "polyphenols" for their benefit. Nutritional supplements, such as vitamins, are marketed by highlighting their benefits. The explanation is very appealing. But let's look at it this way. We'd laugh if the function of a car were redundantly described as "saving people from heart disease," "promoting tourism," or "robbing banks" instead of simply "moving people around quickly". Beyond the idea of trying to sell something unreasonable with all sorts of health claims without knowing exactly what they are, there is the hidden deception of fooling others or being fooled by oneself, and greed. - Joseph’s “just my thoughts”
