4. Shelling seeds with your teeth
What suffers: the teeth and gallbladder.
Sunflower seeds are tasty and useful. But they should be shelled with the hands and never with your teeth. Dentists always recognize experienced seed eaters by very specific tooth damage. People who have gallbladder problems shouldn’t eat them at all, and their caloric value is more than 500 kcal in 100 grams.
5. Chewing on something solid
What suffers: the teeth, gums, and mouth.
People who love chewing on pens, pencils, paperclips, and other solid objects usually have huge enamel problems. This is also why you shouldn’t try to open bottles, chew nuts, ice cubes, and lollipops. More than that, you can get an infection if you do this.
6. Postponing going to the bathroom
What suffers: the kidneys, urinary system, and intestine.
In June 2018, a young gamer from Great Britain was hospitalized after he spent 8 hours playing a game without taking any pauses. His intestines and bladder were so bloated that doctors thought he had a cancer tumor. All doctors agree: you shouldn’t keep it in because if you do, you might injure your muscles which can lead to having a urinary tract infection and constipation.
