Ex-U.S. President George H.W. Bush shaved his head to make a 2-year-old boy feel better. The boy, Patrick, is the son of Mr Bush's bodyguard. He has a blood disease called leukemia. Treatment for leukemia makes people's hair fall out. Bush said he wanted to help Patrick. People say Bush, 89, now looks like Patrick. One said: "It's hard to tell them apart." Mr Bush, and his wife Barbara, gave money to help pay for Patrick's medical bills. People can give money for his expensive treatment on a special website. It was started by Mr Bush's other bodyguards. They also shaved their head.

Mr And Mrs Bush's second child, a daughter, died from leukemia 60 years ago. The little girl was four years old. They worked hard for years after to get money for leukemia research. A clinic called the Robin Bush Child and Adolescent Clinic opened at a hospital in Texas in 2004. Leukemia is a kind of cancer of the blood. It once killed many people, but today people can get treatment at hospital. It's easier to cure children than adults. Anyone can get leukemia. In 2000, around 256,000 children and adults worldwide developed some kind of leukemia, and 209,000 died from it.
