15 000 blinks per day
The fastest muscle in your body is the muscle that lets your eye blink. 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. To care for your eyes, eat carrots. They really do make you see better. Vitamin A is known to prevent “night blindness,” and carrots are loaded with Vitamin A. Deficiency of Vitamin A actually is a significant world problem, comparable to that of protein deficiency and second only to caloric deficiency.
