Seja Bem-Vindo,

"As I write this, it occurs to me that the peculiarity of most things we consider fragile is how they are, in fact, strong. There were tricks we did with eggs, as children, to demonstrate that they are, despite not realizing it, small marble halls capable of withstanding high pressures, and many say that the flapping of a butterfly in the right place can create a hurricane across an ocean. Hearts can be broken, but the heart is the strongest muscle, capable of beating over a lifetime, seventy times a minute, and not almost never fails. Even dreams, which are the most delicate and intangible things, can prove remarkably difficult to kill."
