Banana equivalent dose (BED) is an informal measurement of ionizing radiation exposure, intended as a general educational example to compare a dose of radioactivity to the dose one is exposed to by eating one average-sized banana. Bananas contain naturally occurring radioactive isotopes, particularly potassium-40 (⁴⁰K), one of several naturally-occurring isotopes of potassium. One BED is often correlated to 10⁻⁷ sievert (0.1 μSv); however, in practice, this dose is not cumulative, as the principal radioactive component is excreted to maintain metabolic equilibrium. The BED is only meant to inform the public about the existence of very low levels of natural radioactivity within a natural food and is not a formally adopted dose measurement.

RICE is a mnemonic acronym for the four elements of a treatment regimen that was once recommended for soft tissue injuries: rest, ice, compression, and elevation. It was considered a first-aid treatment rather than a cure and aimed to control inflammation. It was thought that the reduction in pain and swelling that occurred as a result of decreased inflammation helped with healing. The protocol was often used to treat sprains, strains, cuts, bruises, and other similar injuries. Ice has been used for injuries since at least the 1960s, in a case where a 12-year-old boy needed to have a limb reattached. The limb was preserved before surgery by using ice. As news of the successful operation spread, the use of ice to treat acute injuries became common.

The mnemonic was introduced by Dr. Gabe Mirkin in 1978. He withdrew his support of this regimen in 2014 after learning of the role of inflammation in the healing process. The implementation of RICE for soft tissue injuries as described by Dr. Mirkin is no longer recommended, as there is not enough research on the efficacy of RICE in the promotion of healing. In fact, many components of the protocol have since been shown to impair or delay healing by inhibiting inflammation. Early rehabilitation is now the recommendation to promote healing. Ice, compression, and elevation may have roles in decreasing swelling and pain, but have not shown to help with healing an injury.

There are different variations of the protocol, which may emphasize additional protective actions. However, these variations similarly lack sufficient evidence to be broadly recommended. Examples include PRICE, POLICE, and PEACE & LOVE.

Product Red, stylized as (PRODUCT)^RED or (PRODUCT)RED, is a licensed brand by the company Red, stylized as (RED), that seeks to engage the private sector in raising awareness and funds to help eliminate HIV/AIDS in eight African countries, namely Eswatini (formerly Swaziland), Ghana, Kenya, Lesotho, Rwanda, South Africa, Tanzania, and Zambia. It is licensed to partner companies including Apple Inc., Nike, American Express (UK), The Coca-Cola Company, Starbucks, Converse, Electronic Arts, Primark, Head, Buckaroo, Penguin Classics (UK & International), Gap, Armani, FIAT, Hallmark (US), SAP, Beats Electronics, and Supercell. The concept was founded in 2006 by U2 frontman and activist Bono, together with Bobby Shriver of the One Campaign and DATA. The Global Fund to Fight AIDS, Tuberculosis and Malaria is the recipient of Product Red's money.

As part of a new business model, each partner company creates a product with the Product Red logo. In return for the opportunity to increase revenue through the Product Red license, up to 50% of profits gained by each partner is donated to the Global Fund. As Product Red is owned by Red, a portion of the contributions received from the partner brands is assigned as profit. Such an amalgamation of humanitarian aid and for-profit businesses is one example of "ethical consumerism".

In 2012, One Campaign acquired Red as a division of One. Both organizations were co-founded by Bono and Shriver.

Since 2020, Product Red has been used in the global fund to combat the COVID-19 pandemic.

Karoshi (過労死, Karōshi), which can be translated literally as "overwork death" in Japanese, is occupational sudden mortality. The major medical causes of karoshi deaths are heart attack and stroke due to stress and a starvation diet. This phenomenon is also widespread in other parts of Asia.

The Sackler family is an American family who founded and own the pharmaceutical companies Purdue Pharma and Mundipharma. Purdue Pharma, and some members of the family, have faced lawsuits regarding overprescription of addictive pharmaceutical drugs, including OxyContin. Purdue Pharma has been criticized for its role in the opioid epidemic in the United States. They have been described as the "most evil family in America", "drug dealers" and "the worst drug dealers in history".

The Sackler family has been profiled in various media, including the documentary Crime of the Century on HBO, the book Empire of Pain by Patrick Radden Keefe, and the 2021 Hulu mini-series Dopesick.

Calisthenics (American English) or callisthenics (British English) is a form of exercise consisting of a variety of movements that exercise large muscle groups (gross motor movements), such as running, standing, grasping, pushing, etc. These exercises are often performed rhythmically and with minimal equipment, as bodyweight exercises. They are intended to increase strength, fitness, and flexibility, through movements such as pulling, pushing, bending, jumping, or swinging, using one's body weight for resistance. Calisthenics can provide the benefits of muscular and aerobic conditioning, in addition to improving psychomotor skills such as balance, agility, and coordination.

Urban calisthenics is a form of street workout; calisthenics groups perform exercise routines in urban areas. Individuals and groups train to perform advanced calisthenics skills such as muscle-ups, levers, and various freestyle moves such as spins and flips.

Sports teams and military units often perform leader-directed group calisthenics as a form of synchronized physical training (often including a customized "call and response" routine) to increase group cohesion and discipline. Calisthenics is also popular as a component of physical education in primary and secondary schools over much of the globe.

In addition to general fitness, calisthenic exercises are often used as baseline physical evaluations for military organizations around the world. Two examples are the U.S. Army Physical Fitness Test and the U.S.M.C. Physical Fitness Test.

The ketchup as a vegetable controversy stemmed from proposed regulations of school lunches by the USDA's Food and Nutrition Service (FNS) in 1981, early in the presidency of Ronald Reagan. The regulations were intended to provide meal planning flexibility to local school lunch administrators coping with cuts to the National School Lunch Program enacted by the Omnibus Reconciliation Acts of 1980 and 1981. The proposed changes allowed administrators to meet nutritional requirements by crediting food items not explicitly listed. While ketchup was not mentioned in the original regulations, pickle relish was used as an example of an item that could count as a vegetable.

A similar controversy arose in 2011, when Congress passed a bill prohibiting the USDA from increasing the amount of tomato paste required to constitute a vegetable; the bill allowed pizza with two tablespoons (30 mL) of tomato paste to qualify as a vegetable.
