At a speech in Boston, Dr. Neil deGrasse Tyson took a crowd question from a curious 6-and-three-quarters-year-old boy named Jack.
The question was a simple one, "What is the meaning of life?"
Tyson, after a laugh, told Jack that he defines the meaning of life as learning continuously everyday. He added, "For you, at age six and three quarters, may I suggest that... you should explore nature as much as you possibly can."
