Since 1991, the Icelandic Naming Committee has kept an official list of several thousand approved first names. To pick a name that isn't on it, parents must apply: the name has to fit Icelandic grammar, be written with the Icelandic alphabet and be unlikely to embarrass the child. The stated goal is to protect the language. Most Icelanders don't even have a family name, but a patronymic based on a parent's first name, such as Jónsdóttir, 'daughter of Jón'.
That's the estimate from a WHO-led study published in The Lancet in 2024, covering the half-century since the Expanded Programme on Immunization was launched in 1974. It works out to about six lives saved every minute, mostly infants. The measles vaccine alone accounts for around 60% of those lives.
According to the World Gold Council, about 216,000 tonnes of gold have been mined in all of human history. Because gold is so dense (19.3 tonnes per cubic metre), it would fit in a cube about 22 metres on each side, roughly the height of a seven-storey building. Strikingly, about two-thirds of it has been mined since 1950.
