     Forgiving someone who has hurt you or let you down is never an easy thing. Several new studies, however,

say that it could have a lot of health benefits. When you think of forgiveness, you probably don't think of it as

being a health or medical problem. Studies from Stanford University, on the other hand, show that something

like anger can change your well-being.

     When cartoon book characters like the Incredible Hulk get angry, they change colours and often gain special

power. In the real world, anger is less obvious and may be more dangerous. That's why Professor Fred Lufkin,

founder of the Stanford Forgiveness Project and author of Forgive for Good, says holding on to anger and

hatred can harm your physical and mental health. Two new studies seem to show the same idea.

     The studies find that people who are able to forgive feel less stress, less back pain, and less depression.

They also have fewer headaches, lower blood pressure, and fewer problems on sleeping.

     So it doesn't matter if your anger is caused by the traffic or other things. Learning to let it go is important.

Techniques such as deep breath or thought can help. Or just ask yourself if it's worth hurting yourself by

staying angry with someone else.

     Forgiveness does not mean that you simply accept what happened and say it's OK. Instead, it's a way of

making peace with yourself about what happened in the past.
