Swimming lessons
Swimming lessons is the process of learning to swim. In most countries there is a definition of a number of swimming levels that is reached in the process of the curriculum. The respective certificates of swimming tests are required for further training in aquatic abilities. Many countries have defined a minimum swimming level that children should reach by the end of primary education, in most cases with the help of school swimming classes being part of the normal curriculum. Children are often given swimming lessons, which serve to develop swimming technique and confidence. Children were traditionally viewed not to be able to swim independently until 4 years of age, but infant swimming lessons are now recommended to prevent drowning.
Swimming
Swimming is the self-propulsion of a person through fresh or salt water, usually for recreation, sport, exercise, or survival. Locomotion is achieved through coordinated movement of the limbs, the body, or both. Humans can hold their breath underwater and undertake rudimentary locomotive swimming within weeks of birth, as an evolutionary response. Swimming is consistently among top public recreational activities, and in some countries, swimming lessons are a compulsory part of the educational curriculum. As a formalized sport, swimming features in a range of local, national, and international competitions, including every modern summer Olympics.
Aquatic locomotion
Aquatic locomotion is biologically propelled motion through a liquid medium. The simplest propulsive systems are composed of cilia and flagella. Swimming has evolved a number of times in a range of organisms including arthropods, fish, molluscs, reptiles, birds, and mammals. Swimming evolved a number of times in unrelated lineages. Supposed jellyfish fossils occur in the Ediacaran, but the first free-swimming animals appear in the Early to Middle Cambrian. These are mostly related to the arthropods, and include the Anomalocaridids, which swam by means of lateral lobes in a fashion reminiscent of today's cuttlefish.
Diana Nyad
Diana Nyad (née Sneed; born August 22, 1949) is an American author, journalist, motivational speaker, and long-distance swimmer. Nyad gained national attention in 1975 when she swam around Manhattan () and in 1979 when she swam from North Bimini, The Bahamas, to Juno Beach, Florida (). In 2013, on her fifth attempt and at age 64, she became the first person confirmed to swim from Cuba to Florida without the aid of a shark cage, swimming from Havana to Key West (). Nyad was also once ranked thirteenth among US women squash players. Nyad was born in New York City on August 22, 1949, to stockbroker William L. Sneed Jr. and his wife Lucy Winslow Curtis (1925–2007).
Lewis Pugh
Lewis William Gordon Pugh, OIG (born 5 December 1969) is a British-South African endurance swimmer and ocean advocate. He has been described as the "Sir Edmund Hillary of swimming." He was the first person to complete a long-distance swim in every ocean of the world, and he frequently swims in vulnerable ecosystems to draw attention to their plight. Pugh is best known for undertaking the first swim across the North Pole in 2007 to highlight the melting of the Arctic sea ice. In 2010 he swam across a glacial lake on Mount Everest to draw attention to the melting of the glaciers in the Himalayas, and the impact the reduced water supply will have on peace in the region.
History of swimming
Competitive swimming in Britain started around 1830, mostly using breaststroke. Swimming was part of the first modern Olympic games in 1896 in Athens. In 1908, the world swimming association, Fédération Internationale de Natation (FINA), was formed. 10,000-year-old rock paintings of people swimming were found in the Cave of Swimmers near Wadi Sura in southwestern Egypt. These pictures seem to show breaststroke or doggy paddle, although it is also possible that the movements have a ritual meaning unrelated to swimming. An Egyptian clay seal dated between 9000 BC and 4000 BC shows four people who are believed to be swimming a variant of the front crawl.
Tradeoffs for locomotion in air and water
Certain species of fish and birds are able to locomote in both air and water, two fluid media with very different properties. A fluid is a particular phase of matter that deforms under shear stresses and includes any type of liquid or gas. Because fluids are easily deformable and move in response to applied forces, efficiently locomoting in a fluid medium presents unique challenges. Specific morphological characteristics are therefore required in animal species that primarily depend on fluidic locomotion. Because the properties of air and water are so different, swimming and flying have very disparate morphological requirements.

I learned that humans can hold their breath underwater as an evolutionary response? How long do you think you can hold your breath?
Humans can hold their breath underwater and undertake rudimentary locomotive swimming within weeks of birth, as an evolutionary response.

Physiology of underwater diving
Physiology of underwater diving is the physiological influences of the underwater environment on the physiology of air-breathing animals, and the adaptations to operating underwater, both during breath-hold dives and while breathing at ambient pressure from a suitable breathing gas supply. It, therefore, includes both the physiology of breath-hold diving in humans and other air-breathing animals, and the range of physiological effects generally limited to human ambient pressure divers either freediving or using underwater breathing apparatus. Several factors influence the diver, including immersion, exposure to the water, the limitations of breath-hold endurance, variations in ambient pressure, the effects of breathing gases at raised ambient pressure, effects caused by the use of breathing apparatus, and sensory impairment.
Underwater diving
Underwater diving, as a human activity, is the practice of descending below the water's surface to interact with the environment. Immersion in water and exposure to high ambient pressure have physiological effects that limit the depths and duration possible in ambient pressure diving. Humans are not physiologically and anatomically well adapted to the environmental conditions of diving, and various equipment has been developed to extend the depth and duration of human dives, and allow different types of work to be done. In ambient pressure diving, the diver is directly exposed to the pressure of the surrounding water.
Evolutionary psychology
Evolutionary psychology is a theoretical approach in the social and natural sciences that examines psychological structure from a modern evolutionary perspective. It seeks to identify which human psychological traits are evolved adaptations – that is, the functional products of natural selection or sexual selection in human evolution. Adaptationist thinking about physiological mechanisms, such as the heart, lungs, and immune system, is common in evolutionary biology. Some evolutionary psychologists apply the same thinking to psychology, arguing that the modularity of mind is similar to that of the body and with different modular adaptations serving different functions.
Scuba skills
Scuba skills are the skills required to dive safely using self-contained underwater breathing apparatus, (scuba). Most of these skills are relevant to both open circuit and rebreather scuba, and many are also relevant to surface-supplied diving. Those skills which are critical to the safety of the diver may require more practice than is usually provided during training to achieve reliable long-term proficiency  Some of the skills are generally accepted by recreational diver certification agencies as necessary for any scuba diver to be considered competent to dive without direct supervision, and others are more advanced, though some diver certification and accreditation organizations may consider some of these to also be essential for minimum acceptable entry level competence.
Diving safety
The safety of underwater diving depends on four factors: the environment, the equipment, behaviour of the individual diver and performance of the dive team. The underwater environment can impose severe physical and psychological stress on a diver, and is mostly beyond the diver's control. Equipment is used to operate underwater for anything beyond very short periods, and the reliable function of some of the equipment is critical to even short term survival. Other equipment allows the diver to operate in relative comfort and efficiency. The performance of the individual diver depends on learned skills, many of which are not intuitive, and the performance of the team depends on communication and common goals.
Apnea
Apnea or apnoea is suspension of breathing. During apnea, there is no movement of the muscles of inhalation, and the volume of the lungs initially remains unchanged. Depending on how blocked the airways are (patency), there may or may not be a flow of gas between the lungs and the environment; gas exchange within the lungs and cellular respiration is not affected. Voluntarily doing this is called holding one's breath. Apnea can be involuntarily achieved, drug-induced (such as opiate toxicity or tryptamine toxicity), mechanically induced (for example, by strangulation or choking), or it can occur as a consequence of neurological disease or trauma.

Swimming (sport)
Swimming is an individual or team sport that uses arms and legs to move the body through water. The sport takes place in pools or open water (e.g., in a sea or lake). Competitive swimming is one of the most popular Olympic sports, with varied distance events in butterfly, backstroke, breaststroke, freestyle, and individual medley. In addition to these individual events, four swimmers can take part in either a freestyle or medley relay. Swimming each stroke requires specific techniques, and in competition, there are specific regulations concerning the acceptable form for different strokes. There are also regulations on what types of swimsuits, caps, jewelry and injury tape are allowed at competitions.

Sport in India
India is home to a diverse population playing many different sports across the country. Football is a popular sport in some of the Indian states. India has won all the Kabaddi World Cups to date. The country has won eight Olympic gold medals in field hockey. However, cricket is the most popular sport in India. Kabaddi, an indigenous sport is popular in rural India. Several games originated in India including chess, snooker and other regional games. India has won medals in badminton, kabaddi, hockey and many other sports and disciplines. Recently, different forms of martial arts have also gained a lot of prominence in India.
Sports in the United States
Sports in the United States are an important part of the country's culture. Based on revenue, the four major professional sports leagues in the United States are Major League Baseball (MLB), the National Basketball Association (NBA), the National Football League (NFL), and the National Hockey League (NHL). The market for professional sports in the United States is roughly $69 billion, roughly 50% larger than that of all of Europe, the Middle East, and Africa combined. Major League Soccer is sometimes included in a "top five" of leagues of the country. All four enjoy wide-ranging domestic media coverage and are considered the preeminent leagues in their respective sports in the world, although only basketball, baseball, and ice hockey have substantial followings in other nations.
Olympic sports
Olympic sports are sports contested in the Summer and Winter Olympic Games. The 2016 Summer Olympics included 28 sports, with five additional sports due to be added to the 2020 Summer Olympics. The 2014 Winter Olympics included seven sports. The number and kinds of events may change slightly from one Olympiad to another. Each Olympic sport is represented by an international governing body, namely an International Federation (IF). The International Olympic Committee (IOC) establishes a hierarchy of sports, disciplines, and events. According to this hierarchy, the Olympic sports can be subdivided into multiple disciplines, which are often assumed to be distinct sports.
Sport of athletics
Athletics is a collection of sporting events that involve competitive running, jumping, throwing, and walking. The most common types of athletics competitions are track and field, road running, cross country running, and race walking. The results of racing events are decided by finishing position (or time, where measured), while the jumps and throws are won by the athlete that achieves the highest or furthest measurement from a series of attempts. The simplicity of the competitions, and the lack of a need for expensive equipment, makes athletics one of the most commonly competed sports in the world.
Sports in Canada
Sports in Canada consist of a wide variety of games. The most common sports are ice hockey, lacrosse, football, soccer, basketball, curling and baseball, with ice hockey and lacrosse being the official winter and summer sports, respectively. Ice hockey, referred to as simply "hockey", is Canada's most prevalent winter sport, its most popular spectator sport, and its most successful sport in international competition. It is Canada's official national winter sport. Lacrosse, a sport with Indigenous origins, is Canada's oldest and official summer sport. Canadian football is Canada's second most popular spectator sport, being the most popular in the prairie provinces.
