Over 40M people of Irish descent are in the United States, 8x more than the population of Ireland

The Irish people (Irish: Muintir na hÉireann or Na hÉireannaigh) are a nation and ethnic group native to the island of Ireland, who share a common Irish ancestry, identity and culture. Ireland has been inhabited for about 9,000 years according to archaeological studies (see Prehistoric Ireland). For most of Ireland's recorded history, the Irish have been primarily a Gaelic people (see Gaelic Ireland). Anglo-Normans conquered parts of Ireland in the 12th century, while England's 16th/17th century (re)conquest and colonization of Ireland brought a large number of English and Lowland Scots to parts of the island, especially the north. Today, Ireland is made up of the Republic of Ireland (an independent state), and the smaller Northern Ireland (a part of the United Kingdom). The people of Northern Ireland hold various national identities; including Irish, Northern Irish, British, or some combination thereof. The Irish have their own customs, language, music, dance, sports, cuisine,

TIL the first animal to ask an existential question was from a parrot named Alex. He asked what color he was, and learned that it was "grey".

Alex (1976 – 6 September 2007) was an African grey parrot and the subject of a thirty-year (1977–2007) experiment by animal psychologist Irene Pepperberg, initially at the University of Arizona and later at Harvard University and Brandeis University. When Alex was about one year old, Pepperberg bought him at a pet shop. The name "Alex" was a backronym for avian language experiment, or avian learning experiment. Before Pepperberg's work with Alex, it was widely believed in the scientific community that a large primate brain was needed to handle complex problems related to language and understanding; birds were not considered to be intelligent, as their only common use of communication was mimicking and repeating sounds to interact with each other. However, Alex's accomplishments supported the idea that birds may be able to reason on a basic level and use words creatively. Pepperberg wrote that Alex's intelligence was on a level similar to dolphins and great apes. S

TIL taking magic mushrooms, just once ,can permanently change a person's personality, even as an adult

'Magic Mushrooms' May Permanently Alter Personality By Stephanie Pappas, Live Science Contributor Just one strong dose of hallucinogenic mushrooms can alter a person's personality for more than a year and perhaps permanently, a new study finds. People given psilocybin, the compound in "magic mushrooms" that causes hallucinations and feelings of transcendence, demonstrated a more "open" personality after their experience, an effect that persisted for at least 14 months. Openness is a psychological term referring to an appreciation for new experiences. People who are more open tend to have broad imaginations and value emotion, art and curiosity. This personality warp is unusual, said study researcher Katherine MacLean, because personality rarely changes much after the age of 25 or 30. ( In fact, one recent study found that by first grade our personalities are set pretty much for life. ) "This is one of the first studies to show that you actually can
