The muscle that lets your eye blink is the fastest muscle in your body. It allows you to blink 5 times a second. On average, you blink 15 000 times a day. That’s about 10 times per minute, or more than five million times a year. Women blink more than men.
Jean-Dominique Bauby, a French journalist suffering from “locked-in” syndrome, wrote the book “The Driving Bell and the Butterfly” by blinking his left eyelid – the only part of his body that could move.
Animals blink too, of course. Some bird species, usually flightless birds, have only a lower eyelid, whereas pigeons use upper and lower lids to blink. Fish and insects do not have eyelids – their eyes are protected by a hardened lens.
Carrots also contain fiber, potassium, vitamin C, and beta-carotene, which may reduce the risk of heart disease and cancer. Carrots have zero fat content. One carrot provides more than 200% of recommended daily intake of Vitamin A.
Carrots were first cultivated in 500 BC in the Mediterranean regions. The first carrots were purple, white, and yellow. They were introduced in Europe in the 1600s. Orange carrots – the ones we know today – were first grown in Japan in the 17th century, and later made popular by the Dutch.
Mel Blanc, who played the voice of Bugs Bunny, was allergic to carrots.
