Cave diving
Cave diving is underwater diving in water-filled caves. It may be done as an extreme sport, a way of exploring flooded caves for scientific investigation, or for the search for and recovery of divers lost while diving for one of these reasons. The equipment used varies depending on the circumstances, and ranges from breath hold to surface supplied, but almost all cave diving is done using scuba equipment, often in specialised configurations. Recreational cave diving is generally considered to be a type of technical diving due to the lack of a free surface during large parts of the dive, and often involves decompression.
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.
Scuba diving
Scuba diving is a form of underwater diving where the diver uses a self-contained underwater breathing apparatus (scuba) which is completely independent of surface supply, to breathe underwater. Scuba divers carry their own source of breathing gas, usually compressed air, allowing them greater independence and freedom of movement than surface-supplied divers, and longer underwater endurance than breath-hold divers. Open circuit scuba systems discharge the breathing gas into the environment as it is exhaled, and consist of one or more diving cylinders containing breathing gas at high pressure which is supplied to the diver through a regulator.
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.
Tool use by sea otters
The sea otter, "Enhydra lutris", is a member of the Mustelidae that is fully aquatic. Sea otters are the smallest of the marine mammals, but they are also the most dexterous. Sea otters are known for their ability to use stones as anvils or hammers to facilitate access to hard-to-reach prey items. There are three recognized subspecies of otters, all of which exhibit tool use behavior in some capacity. Tool use behavior is more associated with geographic location than sub-species. Most behavioral research has been conducted on "Enhydra lutris nereis", the Californian otter, and some has been conducted on "Enhydra lutris kenyoni", the Alaska sea otter.
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.
Diving
Diving is the sport of jumping or falling into water from a platform or springboard, usually while performing acrobatics. Diving is an internationally recognized sport that is part of the Olympic Games. In addition, unstructured and non-competitive diving is a recreational pastime. Diving is one of the most popular Olympic sports with spectators. Competitors possess many of the same characteristics as gymnasts and dancers, including strength, flexibility, kinaesthetic judgment and air awareness. Some professional divers were originally gymnasts or dancers as both the sports have similar characteristics to diving.

YMCA Philadelphia
YMCA Philadelphia, also the Philadelphia Freedom Valley YMCA was founded on June 15, 1854 by George H. Stuart, a prominent Philadelphia business man and importer. The goal of the Association was to reach “the many thousands of neglected youth not likely to be brought under any moral influence by any other means." The Philadelphia Freedom Valley YMCA is a community service organization that promotes positive values through programs that help to build strong kids, strong families and strong communities. Over the years, the Philadelphia Freedom Valley YMCA has grown to include 15 branches and 55 program sites throughout the Greater Philadelphia area.
Aqua Adventure
Aqua Adventure is a water park located in Central Park in Fremont, California. In 2001, the City Council approved a project to utilize the site of the Puerto Penasco Swim Lagoon into a modern, family-oriented water play facility that would serve both the residents of Fremont as well as the surrounding region. The Family Water Play Facility (also known as the "Water Park") was proposed to be developed on approximately four of the seven acres of the site, which had provided water-oriented recreation to the citizens of Fremont for 32 years prior to closing in 2001. The Water Park would be focused on family fun.

Adult Swim
Adult Swim (stylized as [adult swim]) is the adult-oriented nighttime programming block of the American children's cable network Cartoon Network, operating daily 8 p.m.–6 a.m. Eastern and Pacific Time. It is programmed by Williams Street Productions, a subsidiary of Turner, which also developed two other programming blocks for Cartoon Network: Toonami (which later became a block on Adult Swim in 2012) and Miguzi. The block gets its name from a phrase used by public swimming pools in the United States to label designated times when children are restricted from using the facilities in favor of adults.
List of Shameless characters
The following is a list of fictional characters from the British comedy-drama Shameless, created by Paul Abbott, which began broadcasting on Channel 4 in 2004. The programme is set on the fictinal Chatsworth Estate in suburban Manchester and the surrounding area, and primarily follows the lives of the Gallagher family and the neighbouring Maguire family, and their friends and neighbours in the town's shops and local pub The Jockey. The first series focuses on layabout Frank Gallagher and the lives of his six children, Fiona and boyfriend Steve, Lip, Ian, Carl, Debbie and Liam, and next-door neighbours, Kev and Veronica.
Long-distance swimming
Long-distance swimming is distinguished from ordinary swimming in that the distances involved are longer than are typically swum in pool competitions. When a given swim calls more on endurance than on outright speed, it is the more likely to be considered a long-distance swim. Long-distance swims, however, may take place in pools, such as ultra-long distances swum in 1997 by Grant Robinson and Kelly Driffield (24 hour swims of a 50 m-long pool, approx 100 km). Some of the better-known long-distance swims are crossings of the English Channel, Catalina Channel, Fehmarn Belt and Cook Strait. Ultra-long distance swimming is sometimes referred to as marathon swimming.

History of underwater diving
The history of underwater diving starts with freediving as a widespread means of hunting and gathering, both for food and other valuable resources such as pearls and coral, By classical Greek and Roman times commercial applications such as sponge diving and marine salvage were established, Military diving also has a long history, going back at least as far as the Peloponnesian War, with recreational and sporting applications being a recent development. Technological development in ambient pressure diving started with stone weights (skandalopetra) for fast descent. In the 16th and 17th centuries diving bells became functionally useful when a renewable supply of air could be provided to the diver at depth, and progressed to surface supplied diving helmets - in effect miniature diving bells covering the diver's head and supplied with compressed air by manually operated pumps - which were improved by attaching a waterproof suit to the helmet and in the early 19th century became the standard diving dress.

Diving suit
A diving suit is a garment or device designed to protect a diver from the underwater environment. A diving suit may also incorporate a breathing gas supply (i.e. Standard diving dress or atmospheric diving suit). but in most cases applies only to the environmental protective covering worn by the diver. The breathing gas supply is usually referred to separately. There is no generic term for the combination of suit and breathing apparatus alone. It is generally referred to as diving equipment or dive gear along with any other equipment necessary for the dive. Diving suits can be divided into two classes: "soft" or ambient pressure diving suits - examples are wetsuits, dry suits, semi-dry suits and dive skins, and "hard" or atmospheric pressure diving suits - armored suits that keep the diver at atmospheric pressure at any depth within the operating range of the suit.

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.
Atmospheric diving suit
An atmospheric diving suit (ADS) is a small one-person articulated submersible of anthropomorphic form which resembles a suit of armour, with elaborate pressure joints to allow articulation while maintaining an internal pressure of one atmosphere. The ADS can be used for very deep dives of up to for many hours, and eliminates the majority of physiological dangers associated with deep diving; the occupant need not decompress, there is no need for special gas mixtures, and there is no danger of decompression sickness or nitrogen narcosis. Divers do not even need to be skilled swimmers. Atmospheric diving suits in current use include the Newtsuit, Hardsuit and the WASP, all of which are self-contained hard suits that incorporate propulsion units.
Scuba diving
Scuba diving is a form of underwater diving where the diver uses a self-contained underwater breathing apparatus (scuba) which is completely independent of surface supply, to breathe underwater. Scuba divers carry their own source of breathing gas, usually compressed air, allowing them greater independence and freedom of movement than surface-supplied divers, and longer underwater endurance than breath-hold divers. Open circuit scuba systems discharge the breathing gas into the environment as it is exhaled, and consist of one or more diving cylinders containing breathing gas at high pressure which is supplied to the diver through a regulator.
Rebreather
A rebreather is a breathing apparatus that absorbs the carbon dioxide of a user's exhaled breath to permit the rebreathing (recycling) of the substantially unused oxygen content, and unused inert content when present, of each breath. Oxygen is added to replenish the amount metabolised by the user. This differs from an open-circuit breathing apparatus, where the exhaled gas is discharged directly into the environment. Rebreather technology may be used where breathing gas supply is limited, such as underwater or in space, where the environment is toxic or hypoxic, as in firefighting, mine rescue and high-altitude operations, or where the breathing gas is specially enriched or contains expensive components, such as helium diluent or anaesthetic gases.

Wow those sound so fancy, are they expensive to buy or would you rent one?

definetely rent, they are expensive and have two clases soft flike wetsuits and hard like armored suits
Diving suits can be divided into two classes: "soft" or ambient pressure diving suits - examples are wetsuits, dry suits, semi-dry suits and dive skins, and "hard" or atmospheric pressure diving suits - armored suits that keep the diver at atmospheric pressure at any depth within the operating range of the suit.

Wetsuit
A wetsuit is a garment, usually made of foamed neoprene, which is worn by surfers, divers, windsurfers, canoeists, and others engaged in water sports and other activities in or on water, providing thermal insulation, abrasion resistance and buoyancy. The insulation properties depend on bubbles of gas enclosed within the material, which reduce its ability to conduct heat. The bubbles also give the wetsuit a low density, providing buoyancy in water. Hugh Bradner, a University of California, Berkeley physicist invented the modern wetsuit in 1952. Wetsuits became available in the mid-1950s and evolved as the relatively fragile foamed neoprene was first backed, and later sandwiched, with thin sheets of tougher material such as nylon or later Lycra/Spandex.
Umberto D.
Umberto D. () is a 1952 Italian neorealist film directed by Vittorio De Sica. Most of the actors were non-professional, including Carlo Battisti who plays the title role of Umberto Domenico Ferrari, a poor elderly man in Rome who is desperately trying to keep his rented room. His landlady (Lina Gennari) is evicting him, and his only true friends, the housemaid (Maria-Pia Casilio) and his dog Flike (called 'Flag' in some subtitled versions of the film) are of no help. According to Robert Osborne of Turner Classic Movies, this was De Sica's favorite of all his films. The movie was included in "TIME" magazine's "All-TIME 100 Movies" in 2005.
Murdoch Cameron
Murdoch Cameron (31 March 1847 – 28 April 1930) was Regius Professor of Obstetrics and Gynaecology at the University of Glasgow from 1894 to 1926. He was a pioneer of the Caesarean section under modern antiseptic conditions, becoming world famous after the success of his first Caesarean section at Glasgow Royal Maternity Hospital in 1888. He was honorary President of the first international Congress on Obstetrics and Gynaecology, held in Brussels, in 1892. He was also a founding father of the new Glasgow Royal Maternity Hospital (the Rotten Row) and the father of Samuel James Cameron, Reguis Professor of Midwifery at Glasgow in the 1930s.
Dry suit
A dry suit or drysuit provides the wearer with environmental protection by way of thermal insulation and exclusion of water, and is worn by divers, boaters, water sports enthusiasts, and others who work or play in or near cold or contaminated water. A dry suit normally protects the whole body except the head, hands, and possibly the feet. In hazmat configurations, however, all of these are covered as well. The main difference between dry suits and wetsuits is that dry suits are designed to prevent water entering. This generally allows better insulation making them more suitable for use in cold water.
Battaglione Azad Hindoustan
Battaglione Azad Hindoustan (in Italian: "Battaglione India libera" - "Free India Battalion") was a foreign legion unit formed in Fascist Italy under the "Raggruppamento Centri Militari" in July 1942. The unit, raised initially as "Centro I", was headed by Mohammad Iqbal Shedai – a long term Indian resident of Rome – and was formed of Indian ex-prisoners-of-war from India. Raised along with units dedicated to Tunisia ("Centro T") and the Arabs ("Centro A"), it was tasked to intelligence gathering and sabotage operations behind enemy lines. A part of "Centro I" was renamed "Battaglione Azad Hindoustan" in August 1942 when the "Raggruppamento Centri Militari" itself was redesignated as "Raggruppamento Frecce Rosse" ("Red Arrows group").
Starship Troopers
Starship Troopers is a military science fiction novel by U.S. writer Robert A. Heinlein. Written in a few weeks in reaction to the U.S. suspending nuclear tests, the story was first published as a two-part serial in "The Magazine of Fantasy & Science Fiction" as Starship Soldier, and published as a book by G. P. Putnam's Sons in December 1959. The story is set in a future society ruled by a world government dominated by a military elite. The first-person narrative follows Juan "Johnny" Rico through his military service in the Mobile Infantry. Rico progresses from recruit to officer against the backdrop of an interstellar war between humans and an alien species known as "Arachnids" or "Bugs".
