With modem dating techniques，the scientists soon learned that the iceman was about 5，300 years old.Born in about 3300 B.C.，he lived during the Bronze Age in Europe.At first scientists thought he was probably a hunter who had died from an accident in the high mountains.More recent evidence，however，tells a different story.A new kind of X-ray shows an arrowhead still stuck in his shoulder.It left only a tiny hole in his skin，but it caused internal damage and bleeding.He almost certainly died from this wound，and not from the wound oil the back of his head.This means that he was probably in some kind of battle.It may have been part oi a large war，or he may have beenfightiing bandits.He may even have been a bandit himself.
