The British Medical Journal recently did some serious myth-busting (see part one and part two). Apparently, all of the following are myths:

• Sugar causes hyperactivity in children
• Suicides increase over the holidays
• Poinsettia is toxic
• Not wearing a hat causes excess heat loss
• Eating late in the day makes you fat
• You can cure a hangover
• People should drink at least eight glasses of water a day
• We use only 10% of our brains
• Hair and fingernails continue to grow after death
• Shaving hair causes it to grow back faster, darker, or coarser
• Reading in dim light ruins your eyesight
• Eating turkey makes people especially drowsy
• Mobile phones create considerable electromagnetic interference in hospitals.

Fascinating…
