Here are five common myths debunked with facts:
1. Myth: Cracking Your Knuckles Causes Arthritis
- Fact: Studies have shown that cracking your knuckles does not cause arthritis. The popping sound comes from gas bubbles forming and collapsing in the synovial fluid of the joint. However, excessive knuckle cracking may weaken grip strength over time.
2. Myth: Goldfish Have a 3-Second Memory
- Fact: Goldfish actually have a memory span of months. They can recognize their owners, remember feeding times, and even learn tricks, proving they are much smarter than the myth suggests.
3. Myth: Sugar Makes Kids Hyperactive
- Fact: Numerous scientific studies have found no direct link between sugar consumption and hyperactivity in children. The belief likely comes from the excitement of events where sugary treats are consumed, such as birthday parties.
4. Myth: The Great Wall of China Is Visible from Space
- Fact: While impressive, the Great Wall is not easily visible from space without aid. Astronauts confirm that it's difficult to see with the naked eye, especially since it blends into the surrounding landscape.
5. Myth: Humans Swallow Spiders While Sleeping
- Fact: There is no scientific evidence to support this claim. Spiders tend to avoid humans, as the vibrations from breathing and movement scare them away. The idea that we swallow multiple spiders a year is purely an urban legend.
