A son says to his father: “Dad, would you be willingly to run a marathon with me?” The father, despite his age and a heart disease, said “YES”. And so they ran that marathon, together.
The son asks: “Dad, can you run another marathon with me?” Again father said “YES”. So they ran another marathon, together.
One day the son asks his father: “Dad would please do the Iron Man with me?” Now just in case you wouldn’t know, The Iron Man is the toughest triathlon in existence; 4km swimming, then 180 km by bike, and finally another 42 km running, in one stroke.
Again father said “YES”
