Seven Myths from Medicine

In a recent article, Vreeman and Carroll expose seven medical myths:

• You should drink eight glasses of water a day.
• You only use 10% of your brain.
• Your hair and fingernails grow on after you die.
• Shaving your hair causes it to grow back darker and coarser.
• If you read in dim light, you will ruin your eyes.
• Eating turkey makes you sleepy.
• Using a mobile phone in a hospital can affect other equipment

They go on to debunk each of the myths above. Interestingly, these myths persist despite evidence to the contrary. I wonder if similar myths exist in psychology.
