"I think you should take a break, Dad," Hawk says gingerly, not wanting Ayn to misjudge this statement as an attack on his hardcore science-ing. The boy notice how strange their dad's brown eyes are. How bloodshot. How sunken-looking due to poor sleep and over-thinking. And there is nothing new or even surprising about that since their dad is a great scientist. Professor Ayn is a living think tank. A great deep thinker. A brainiac, if there really is such a word as funny as that. And just like those famous professional writers and playwrights living in this time and age, scientists also use their creativity for a living. And most of the time scientist like their dad prefers thinking a lot, toying about an idea a lot to the point of figuratively tearing and wearing their brain tissues.
