Scuba breathing systems are really complex. There can be either closed or semi-closed circuit rebreathers. This allows air to be recylced
Closed-circuit or semi-closed circuit rebreather scuba systems allow recycling of exhaled gases.

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.
Scuba set
A scuba set is any breathing apparatus that is carried entirely by an underwater diver and provides the diver with breathing gas at the ambient pressure. (Scuba is an anacronym for self-contained underwater breathing apparatus.) Although strictly speaking the scuba set is only the diving equipment which is required for providing breathing gas to the diver, general usage includes the harness by which it is carried, and those accessories which are integral parts of the harness and breathing apparatus assembly, such as a jacket or wing style buoyancy compensator and instruments mounted in a combined housing with the pressure gauge, and in the looser sense it has been used to refer to any diving equipment used by the scuba diver, though this would more commonly and accurately be termed scuba equipment.
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 regulator
A diving regulator is a pressure regulator that reduces pressurized breathing gas to ambient pressure and delivers it to the diver. The gas may be air or one of a variety of specially blended breathing gases. The gas may be supplied from a scuba cylinder carried by the diver or via a hose from a compressor or high pressure storage cylinders at the surface in surface-supplied diving. A gas pressure regulator has one or more valves in series which reduce pressure from the source, and use the downstream pressure as feedback to control the rate of flow and thereby the delivered pressure, lowering the pressure at each stage.
Rebreather diving
Rebreather diving is underwater diving using rebreathers, which recirculate the breathing gas already used by the diver after replacing oxygen used by the diver and removing the carbon dioxide metabolic product. Rebreather diving is used by recreational, military and scientific divers in applications where it has advantages over open circuit scuba, and surface supply of breathing gas is impracticable. The main advantages of rebreather diving are extended gas endurance, and lack of bubbles. Rebreathers are generally used for scuba applications, but are also occasionally used for bailout systems for surface supplied diving.
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.
Recreational diving
Recreational diving or sport diving is diving for the purpose of leisure and enjoyment, usually when using scuba equipment. The term "recreational diving" may also be used in contradistinction to "technical diving", a more demanding aspect of recreational diving which requires greater levels of training, experience and equipment to compensate for the more hazardous conditions associated with the disciplines. Breath-hold diving for recreation also fits into the broader scope of the term, but this article covers the commonly used meaning of "scuba diving for recreational purposes, where the diver is not constrained from making a direct near-vertical ascent to the surface at any point during the dive".

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.
Technical diving
Technical diving (also referred to as tec diving or tech diving) is scuba diving that exceeds the agency-specified limits of recreational diving for non-professional purposes. Technical diving may expose the diver to hazards beyond those normally associated with recreational diving, and to greater risk of serious injury or death. The risk may be reduced by appropriate skills, knowledge and experience, and by using suitable equipment and procedures. The skills may be developed through appropriate specialised training and experience. The equipment often involves breathing gases other than air or standard nitrox mixtures, and multiple gas sources.
Buddy diving
Buddy diving is the use of the buddy system by scuba divers and is a set of safety procedures that are intended to improve divers' chances of avoiding or surviving accidents in or under water by diving in a group of two or sometimes three divers. When using the buddy system, members of the group dive together and co-operate with each other, so that they can help or rescue each other in the event of an emergency. This is most effective if the divers are both competent in all the relevant skills and are sufficiently aware of the situation to be able to respond in time, which is a matter of both attitude and competence.
Human factors in diving safety
Human factors are the physical or cognitive properties of individuals, or social behavior which is specific to humans, and influence functioning of technological systems as well as human-environment equilibria. The safety of underwater diving operations can be improved by reducing the frequency of human error and the consequences when it does occur. Human error can be defined as an individual's deviation from acceptable or desirable practice which culminates in undesirable or unexpected results. Dive safety is primarily a function of four factors: the environment, equipment, individual diver performance and dive team performance.

Awesome! So you would have plenty of people around to teach you how to do it safely! There are alot of skills that come from classes and are kind of counter intuitive.

Ma'alot-Tarshiha
Ma'alot-Tarshiha (; , "Maʻālūt Taršīḥā") is a mixed city in the North District in Israel, some east of Nahariya, about above sea level. The city was established in 1963 through a municipal merger of the Arab town of Tarshiha and the Jewish town of Ma'alot. In the city has a population of . Excavations of a 4th-century burial cave in the village unearthed a cross and a piece of glass engraved with a menorah. Crusader sources from the 12th and 13th century refer to Tarshiha as "Terschia," "Torsia" and "Tersigha." The King had initiated the settlement of Crusader ("Latin", "Frankish") people in nearby Mi'ilya ("Castellum Regis"), and from there settlement spread out to Tarshiha.

Grief
Grief is a multifaceted response to loss, particularly to the loss of someone or something that has died, to which a bond or affection was formed. Although conventionally focused on the emotional response to loss, it also has physical, cognitive, behavioral, social, cultural, spiritual and philosophical dimensions. While the terms are often used interchangeably, "bereavement" refers to the state of loss, and "grief" is the reaction to that loss. Grief is a natural response to loss. It is the emotional suffering one feels when something or someone the individual loves is taken away. The grief associated with death is familiar to most people, but individuals grieve in connection with a variety of losses throughout their lives, such as unemployment, ill health or the end of a relationship.
List of Parks and Recreation characters

The protagonist is Leslie Knope (Amy Poehler), the deputy parks director as well as serving on city council, and the rest of the ensemble cast consists of her friends and co-workers, including nurse Ann Perkins (Rashida Jones), parks director Ron Swanson (Nick Offerman), and parks department employees Tom Haverford (Aziz Ansari), April Ludgate (Aubrey Plaza), Andy Dwyer (Chris Pratt), Jerry Gergich (Jim O'Heir), and Donna Meagle (Retta).
Ma'alot massacre
The Ma'alot massacre was a Palestinian terrorist attack that occurred in May 1974 and involved a two-day hostage-taking of 115 Israeli people which ended in the murders of over 25 hostages. It began when three armed members of the Democratic Front for the Liberation of Palestine (DFLP) entered Israel from Lebanon. Soon afterwards they attacked a van, killing two Israeli Arab women while injuring a third and entered an apartment building in the town of Ma'alot, where they killed a couple and their four-year-old son. From there, they headed for the Netiv Meir Elementary School, where they took more than 115 people (including 105 children) hostage on 15 May 1974, in Ma'alot.
Ma'alot Dafna
Ma'alot Dafna () is an Israeli settlement and neighborhood in Jerusalem that sits partly in East Jerusalem and in a territory that was no man's land before the Six Day war. It borders the neighborhood of Shmuel HaNavi to the west, Ammunition Hill to the east, Ramat Eshkol to the north and Arzei HaBira to the south. The international community considers Israeli settlements in East Jerusalem illegal under international law, but the Israeli government disputes this. Ma'alot Dafna was established in 1972 on the hillside through which Israeli troops in the Six Day War made their way from the Israeli neighborhood of Shmuel HaNavi to fight the Arab Legion troops at the Battle of Ammunition Hill.
