Maybe it was never forgotten , but instead it wa kept as a secret for centuries , and the black plague was brought to Europe when a ship from the Americas arrived in Sicily in 1347 . <| sep |> My parents bought us a Genesis when I was about six years old , and under the promotion they bought it under , we would recieve Sonic 2 in the mail once it was released . When we finally got it , i was totally blown away . All my scribblings in class became drawings of sonic and tails . I think it was the first game I ever beat , if I ' m being honest . A lot of fond memories of that one . <| sep |> I assume these tiny blue dots are sanctuary cities ? <| sep |> 1 on the reebok Nanos . Best for the gym . <| sep |> It ' s common knowledge to some people , or they already know instinctively , but my mind was really blown by Dunbar ' s number . Primate ' s brain size is directly related to the number of individuals in their tribes . The human brain size points to a maximum tribe size of 150 people . And even if that estimate is off , there ' s definitely a limit to the number of people we can really care about . That ' s why you only feel a vague sadness when a tsunami kills thousands on the other side of the world . That ' s why social movements or touching news stories or anything that makes you really feel for an issue singles out one person . That photo of the little Syrian boy that drowned . The Rosa Parks story . Etc So any time someone hates a group of people , or engages in tribalism , they ' re just falling victim to Dunbar ' s number . They don ' t see individual people among the others .
