"Your son is having a hereditary heart disease."

"What should we do, Doc? Please, help him..."

"Nothing could stop this disease. The worse thing is... I predicted he won't be able to live until he reach his 20. All things that you can do are, keep him away from physical exercise. It is going to be a danger."

His mom cried. He listened to every words that the doctor said.

Died at his 20th...

That was his biggest fear.
