First skyscraper 🏙
- Before 1884, all buildings were short, all men were tall, and the sky was much closer to earth. Or at least it felt that way until the Home Insurance Building was erected in downtown Chicago.
At 10 stories and 136 feet tall, the steel-and-brick structure became the first official skyscraper. It was demolished in 1931.

First pedestrian hit and killed by a car 🚙
- In a day and age where pedestrians getting hit by cars has unfortunately become so routine it hardly even makes the news anymore, it can be easy to forget that there had to have been a first person to be killed by those new-fangled mechanical horses. And that person was Bridget Driscoll when she was struck down by a demonstration car on August 17, 1896.
The car was traveling at four miles per hour which makes it even harder to understand how the tragedy happened. The coroner said he hoped “such a thing would never happen again.” Hmm.

- If a child’s entire circulatory system—we’re talking veins, arteries, and capillaries—were laid out flat, it would stretch for more than 60,000 miles, according to the Franklin Institute.
By the time we reach adulthood, our bodies have become home to approximately 100,000 miles of blood vessels.
