Found this pretty interesting. It lists, as the title implies, 20 things you did not know about death. Here are a few of my favourites.
1 The practice of burying the dead may date back 350,000 years, as evidenced by a 45-foot-deep pit in Atapuerca, Spain, filled with the fossils of 27 hominids of the species Homo heidelbergensis, a possible ancestor of Neanderthals and modern humans.
5 The trigger of death, in all cases, is lack of oxygen. Its decline may prompt muscle spasms, or the “agonal phase,” from the Greek word agon, or contest.
7 So much for recycling: Burials in America deposit 827,060 gallons of embalming fluid—formaldehyde, methanol, and ethanol—into the soil each year. Cremation pumps dioxins, hydrochloric acid, sulfur dioxide, and carbon dioxide into the air.
8 Alternatively . . . A Swedish company, Promessa, will freeze-dry your body in liquid nitrogen, pulverize it with high-frequency vibrations, and seal the resulting powder in a cornstarch coffin. They claim this “ecological burial” will decompose in 6 to 12 months.
12 If this doesn’t work, we’re trying in vitro! In Madagascar, families dig up the bones of dead relatives and parade them around the village in a ceremony called famadihana. The remains are then wrapped in a new shroud and reburied. The old shroud is given to a newly married, childless couple to cover the connubial bed.
13 During a railway expansion in Egypt in the 19th century, construction companies unearthed so many mummies that they used them as fuel for locomotives.
16 Waiting to exhale: In 1907 a Massachusetts doctor conducted an experiment with a specially designed deathbed and reported that the human body lost 21 grams upon dying. This has been widely held as fact ever since. It’s not.
20 It is estimated that 100 billion people have died since humans began.
