A journey to the roof of the world.

An 80-year-old Japanese mountaineer, Yuichiro Miura, has become the oldest man to reach the summit of Everest.

The octogenarian has climbed the mountain twice before.

But Mr Miura's record could be short-lived; an 81-year-old Nepalese climber is preparing to make his ascent this week.
