Here are the key facts extracted from the text:
1. Approximately 57 million people are expected to die this year.
2. Two-thirds of deaths are due to aging, a mysterious and incurable disease.
3. Aging is not a direct cause of death, but it weakens the body, making it more susceptible to lethal conditions.
4. The exact reason for aging is unknown, but it is believed to be a combination of multiple interconnected factors.
5. Telomeres, the limits on cell division, may imply that obsolescence is programmed into our DNA.
6. Manipulation of specific genes in other animals can have drastic effects on the aging process.
7. Caloric restriction has been shown to potentially extend longevity in some studies.
8. The fear of death is known as thanatophobia.
9. Death is the cessation of brain activity followed by natural decomposition of the body.
10. Some ancient cultures personified death in a less menacing fashion, such as the Greek god Thanatos.
11. The modern depiction of the Grim Reaper as a menacing skeleton may have originated from the Black Death pandemic.
12. A unit of measurement called a micromort (µmt) measures the probability of sudden death in any given context.
13. 1 µmt is equivalent to a 1 in 1,000,000 chance of death.
14. Skydiving is rated at approximately 7 µmt per jump.
15. Riding a bike for 10 km, driving a car for 400 km, or flying with commercial airlines for 10,000 km exposes you to 1 µmt of risk.
16. The presidency is considered the deadliest job in America, with a risk of 186,000 µmt.
17. Between 10-20% of cardiac arrest survivors recall near-death experiences.
18. Near-death experiences often involve a sense of peace, love, and happiness, and may include interactions with deceased loved ones or supernatural entities.
19. Studies have found that near-death experiences are largely culture-dependent.
20. The hydra is a tiny freshwater animal that exhibits biological immortality, showing no signs of aging or adverse effects associated with it.
21. Other creatures, such as jellyfish, lobsters, and flatworms, also exhibit some form of biological immortality.
22. Cotard Syndrome is a rare mental disorder in which patients deny the existence of one or multiple body parts, and in extreme cases, deny their own existence.
23. In some cases, patients with Cotard Syndrome believe they are already dead and therefore cannot die.
24. A company called Rent A Mourner offers a service where random people attend a funeral and act as if they mourn the deceased.
25. Thomas Bradford attempted to prove the existence of an afterlife by committing suicide and communicating with his spiritualistic accomplice from beyond the grave.
26. Cryonics is a practice where the body is frozen in the hopes of future revival.
27. Over 250 individuals have undergone cryopreservation, and thousands more plan to do so.
28. In 2016, scientists successfully restored a frozen rabbit brain to near-perfect condition, demonstrating the feasibility of subzero preservation.
