     An 11-year-old schoolboy is ageing (变老) five times faster than his friends because of a strange

illness, which is often seen in old men. Now he is fighting against it.

     Harry Crowther's bones (骨头) have started to break into small pieces, and he has poor body

condition (状况). However, he does not let it stop him from being an energetic teenager.
