I'm not an expert but here's my humble opinion. Being an astronaught has very stringent physical and mental requirements. It's probably easier(or cheaper) to pick the smartest candidates from a group of very fit ones. To make a very crude analogy, it's easier to turn the star QB into a valedictorian than to turn the valedictorian into a QB. Ps. I love the verb grok. Such a great book. |
