Life extension is the idea of extending the human lifespan, either modestly – through improvements in medicine – or dramatically by increasing the maximum lifespan beyond its generally settled limit of 125 years. The ability to achieve such dramatic changes, however, does not currently exist.

Some researchers in this area, and "life extensionists", "immortalists" or "longevists" (those who wish to achieve longer lives themselves), believe that future breakthroughs in tissue rejuvenation, stem cells, regenerative medicine, molecular repair, gene therapy, pharmaceuticals, and organ replacement (such as with artificial organs or xenotransplantations) will eventually enable humans to have indefinite lifespans (agerasia) through complete rejuvenation to a healthy youthful condition. The ethical ramifications, if life extension becomes a possibility, are debated by bioethicists.

The sale of purported anti-aging products such as supplements and hormone replacement is a lucrative global industry. For example, the industry that promotes the use of hormones as a treatment for consumers to slow or reverse the aging process in the US market generated about $50 billion of revenue a year in 2009. The use of such products has not been proven to be effective or safe.

Sogen Kato (加藤 宗現, Katō Sōgen; 22 July 1899 – c. November 1978) was a Japanese man thought to have been Tokyo's oldest man until July 2010, when his mummified corpse was found in his bedroom. It was concluded he had likely died in November 1978, aged 79, and his family had never reported his death. Relatives had rebuffed attempts by ward officials to see Kato in preparations for Respect for the Aged Day later that year, citing many reasons from him being a "human vegetable" to becoming a sokushinbutsu (Buddhist mummy). An autopsy could not determine the cause of Kato's death.

The discovery of Kato's remains sparked a search for other missing centenarians lost due to poor recordkeeping by officials. A study following the discovery of Kato's remains found that police did not know if 234,354 people over the age of 100 were still alive. Poor recordkeeping was to blame for many of the cases, officials admitted. One of Kato's relatives was found guilty of fraud; his relatives claimed ¥9,500,000 (US$117,939; £72,030) of the pension meant for Kato.
