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”
Rice has been the staple crop of the East, while wheat has been the staple of the West. Rice requires more water to produce than wheat. Rice farmers had to contend with the availability of water, which favored collective farming. Wheat could be grown with less labor than rice. Rice farmers lived collectively, while wheat farmers lived individually. Collective agriculture led to the development of societies that were governed by village rules. On the other hand, individual agriculture led to cultures that valued personal freedom and respect for individuality over communal rules. Patterns of agriculture have indisputably influenced social structure and culture. - Joseph’s “just my thoughts”
