Most people aren't thankful for having a full body.
Why? What do you think?
Can you imagine yourself if you don't have a full body and what will you do?
There is a man whose name is "Hirotada Ototake". He was born with no arms and legs. When he was born, he had just his body and head. The cause is unknown. However, he has a good home enviroment, great parents, teachers, and friends. This made it possible to do a lot of things.
For exsample, here is one episode. when he was a junior high school student, he applied to join a basketball club. Of course he couldn't run fast, dribble, and shoot. At that time he had very small arms and legs (each about 10cm). He tried to dribble and he practiced a lot. Then he was able to dribble and he played game with his teammate. Unfortunately, I can't explain his whole story. Now, he is 32 years old and he wrote some books. He sais " I'm happy. Being handicap is inconvenient but not unhappy." in his book. He was broken many walls and he went to "Waseda University(which is a top flight University in Japan)". And now, he has a child and he works at an elementary school as a teacher. He has many abilities.
His books translated in English, Chinese, Koria, and maybe some other language.You can read his books if you want.
