頭髮

The function of hair disappears, their intelligence would drop to near idiocy! There are many creatures on Earth, but only humans have hair. And the structure of this hair is so marvelous - each strand is hollow inside with extremely intricate organization. Is the function of hair to protect the head? But human skulls are nearly an inch thick and extremely hard - so what is the soft hair for? Three 'ancient objects,' three strange dreams, a mysterious seven-story stone chamber, and a tribe reduced to a single member lead Wisely on a trail of investigation in Nepal. In the end, he not only discovers the true function of 'hair' for humans, but also discovers that humanity's home is not Earth at all! Written in 1978, The Hair holds special significance in the Wisely series - it was the first story written after a six-year hiatus.
