The Bible is the world’s best-selling and most widely distributed book. Its name comes from the Koine Greek “Ta Biblia”, which means “the books”. It’s a collection of 66 books written by around 40 authors over approximately 1,500 years.

Originally there was no division of chapters and verses. But in order to facilitate studying and referencing specific parts of the text, these divisions were developed. In around 1227, Stephen Langton, an Archbishop of Canterbury, divided the Bible in chapters. In 1553, Robert Estienne published the first Bible with his verse system, which is the one used until today.

An important way to prevent the spread of COVID-19 is social distancing. This strategy was followed all around the world, Brazil included. However, the distancing is being weakened over time, which made me think: do states with better education follow the distancing longer?

At first, this question may look nonsense, but having in mind that the poor knowledge of how viruses work and the spread of fake news make people care less about preventive measures, maybe states that offer a better education will have more aware people.

Of course things aren’t so simple, there are many other aspects that influence…
