A good motive for studying Physics with desire and fondness

Of course more than once you will have heard like pupil or like teacher "Why there serves to study this, what application it has". Well, today I bring to you a good motive for studying Physics with desire and fondness.
Let's see: if I say to you "blood pressure and law of Laplace:" how many of you are you capable of relating both concepts? I put myself a moment the disguise of blue bug comegalletas and I you it count step to pasito:1. The blood pressure is the force with which the blood circulates along the blood glasses.
2. The arterial tension is the force, the resistance that the blood glasses put up against the step of it bleed 3. We lack the third element: the radio of the blood glasses. Do you remember when érais children and jugábais to press a hose and to see how was the water going out to major pressure?
4. Let's go now for the Laplace law: The pressure is equal to the tension divided by the radio. I dress of nice form:
Throwing a glance to the equation we realize that if it diminishes the radio, the blood pressure increases and if it raises the tension, also it raises the pressure.
With these notes you already have material sufficient to throw yourselves to think what happens when a pesona suffers aterosclerosis (the arteries become more rigid) or any other example related to this that occurs to you. I wait for you in the comments to debate and to explain why of the things. Dedicated tenderly to Sergio L. Palaces, Wis and Eugenio, in so many good moments that have met to me on his earnings on Physics :)
