Medical mythbusters

BMJ busts some medical myths here and here. Among them:

1. You should drink at least eight glasses of water a day,

2. Sugar causes hyperactivity in children,

3. We use only 10% of our brains,

4. Eating turkey makes you drowsy,

4. You lose most of your body heat through your head, and

5. Eating at night makes you fat

It ain’t the things you don’t know that hurt you, it’s the things you know that just ain’t so.
