A FATHER'S LOVE for his son...........

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 kms swimming, 180 kms bikin, 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.... ?

Such is the love a father gives to his son - what then should sons do for their fathers?
