There were once 3 brothers who went to different universities in order to learn. Each came back with a different wisdom. One developed a television-like unit that could see great distances. The second invented an air travel machine that traversed great distances in no time at all. The other brother discovered a natural healing formula which could cure a broad variety of maladies.
One day while viewing his video screen, the first brother discovered that a King’s daughter was deathly ill. The youngest brother immediately contacted his sibling who transported him and his elixir to the capital city. The treatment was effective and the princess returned to good health.
"Had I not seen the problem on my video the worst would have happened" claimed the first brother. "Without the speed of my aircraft we would have arrived at the palace too late" said the second.
"Yes," agreed the youngest, "However without my medicine nothing could have saved her."
The King, seeing some validity in each argument-turned to the princess and asked her to choose.
"As far as the past is concerned, you all contributed to my salvation," she observed," but as far as my future is concerned, should I suffer are lapse, it is the elixir that I will need"
