I remember hearing a story in one of the Chicken Soup books about a family in some kind of war camp.

They were all ill, and a good soul kept mailing them some life savers. With time, they got better.

Little did they know these "life savers" were actually CANDIES.

I truly believe in mind over matter.

Once when I fell off of a horse and broke my wrist, I just laid there saying "it doesn't hurt, it doesn't hurt" in my head.. and it helped the pain a bit. Weird! Maybe it was just me, though.
