The Funny Facts of Anatomy

What makes someone left handed or right handed?

If you are left-handed, you are the odd man out. Only 11% of the world population is left-handed. You can easily see how few lefties there are by the vast number of right-handed gadgets, cooking tools that only fit comfortably in the right hand, and awkwardly designed desks. In fact, around 2,000 left-handed people die annually due to improper use of equipment designed only for those who are right-handed.

So what causes someone to become left-handed? Scientists aren’t sure, but research points to a combination of genes and environment. Genes that cause left-handedness have not been discovered, but it has been found that people who dominantly use their left hands do have more left-handed family members. And although genes haven’t been found, scientists have discovered the wirings are different in the brains of righties versus lefties.

Is it true that a sneeze comes out at 100 mph?

A long-standing estimate and scientific theory pin the velocity of a sneeze at roughly 100 miles per hour, but that appears to be a gross exaggeration.

Recent studies, as well as an experiment on the Discovery show Mythbusters, found that a sneeze clocks in way less than 100 mph. The study’s found that a sneeze’s maximum velocity is nowhere near 100 mph but an average of 10 mph, with some clocking in at 35 mph. It’s a cough that might get a speeding ticket with air that moves at speeds up to 60 mph.

How much hair loss in normal?

We lose an average of 50 to 100 strands of hair a day. However, the exact number varies with the individual and can be increased due to a variety of factors. Medications and chemicals introduced into our body can affect the hair’s growth phases and increase the rate of hair loss.

If you’re seeing bald patches or thinning, stress, diet, medication, cigarette smoking, thyroid, or hormone levels could be to blame. Don’t stress if you’re losing more, some may lose up to 150 a day and still be healthy. We are all born with a set amount of hair follicles, but it varies with natural hair color. Blondes have more than those with darker hair with an average of 150,000 hairs. Those with black or brown hair average 110,000 to 100,000 hairs. The average redhead has 90,000.

How do I know if I have intestinal parasites?

Intestinal parasites, which are tiny organisms that are usually worms, feed off of the nutrition in your intestine. Some examples of parasites include roundworms, pinworms, whipworms, tapeworms, and hookworms. Parasites come in so many different shapes and sizes and can cause a very wide range of problems. You can contact parasites from contaminated food and water, undercooked meat, contaminated lake water, or unclean or contaminated fruits and vegetables.

Several signs of intestinal parasites could be:

  • Aching muscles or joints
  • Fatigue, depression, and apathy
  • Unexplained rashes
  • Iron deficiency, anemia
  • History of food poisoning or traveler’s diarrhea with recurrent digestion issues
