The world around us is amazing and diverse. Sure, it’s impossible to know everything about it, but some things are so obvious that we should feel slightly ashamed of not knowing them.
We have gathered some elementary facts that can come in useful in life. They absolutely deserve to be more widely known.
Antibiotics are useless against flu, colds, and other viruses.
- What we think: A doctor can prescribe antibiotics to fight colds and flu.
- Reality: Antibiotics do not work on viruses because they are made to treat bacterial infections. Viruses are structurally different from bacteria and have a different genesis. Therefore, antibiotics are powerless against flu, acute respiratory infections, and signs of the common cold such as coughing, sore throat, runny nose, etc.
Headphones can serve as a microphone.
- What we think: To make a sound record on an ordinary computer, you absolutely need special equipment.
- Reality: If the quality doesn’t matter too much, you can use any pair of headphones. Just plug them into your computer’s or laptop’s input, hit record, and start talking into the earpiece.
