How much can love be?

Editor's note: Someone forwarded this to me. I am so touched, and I believe you will too. Enjoy...

Dear All,
It is good story to share with my friends!
How much can love be?

This is the most touching and inspiring video ever...

One day, a son asks his dad "Daddy, would you like to run a marathon with me?"

The father says "yes". And they run their first marathon together.

Another time, the son asks his dad again "Daddy, would you like to run a marathon with me?
The father says "yes son".

One day, the son asks his father "Daddy, would you run the Ironman with me?"
The Ironman is the most difficult triathlon ever (4 km swimming, 180 km biking, 42 km running?)
And the dad says "yes".

The story looks simple until you watch the following clip.
Just amazing, how much can love be....
