Cuando un mecánico te dice que tu coche funcionaría mejor con fanta naranja que con gasolina, no se lo discutes, porque él es el que sabe de coches. Y cuando una nutricionista dice que la obesidad se previene o se trata con una resta, no se lo discutes, porque ella es la que sabe de fisiología, de física y de matemáticas.
(Citizen) Why do you think the man fell off the cliff?
(Policeman) Obviously the force upward was smaller than the force downward. Don’t you know about Newton’s laws of physics?
(Citizen) Yeah, of course. But I am asking about the real cause. I think saying than something falls is the same as saying that the resulting force goes downwards. What I am asking is why did the man fell. Was it an accident? Was he pushed off?
(Policeman) Are you deaf? It is a law of the universe: he fell because the force upward was smaller than the force downward. And he stopped falling when the forces upward and downward eventually got balanced.
(Citizen) Nothing to do with hitting the rock bottom, I guess.
(Policeman) It’s science, sir. It’s all about controlling your forces.
Bottom line 1: if you don’t want to fall off the cliff you should increase your force upward or decrease your force downward. Having a hot discussion on the top of the cliff with your worst enemy, who happens to be a serial killer, is irrelevant.
Bottom line 2: if someone tells you that you get fat because your Calories In are bigger than your Calories Out, smile, breathe deeply, and run! (away from the cliff is encouraged)
