Veteran alpinist Yuichiro Miura has set his sights on a target no one has ever achieved — reaching the summit of Mount Everest at the age of 80.

"It may be that I can surpass some human limits," Miura said when he announced the challenge, slated for this spring, at a news conference on his 80th birthday on Oct. 12. He was wearing red, the color men put on to celebrate their 60th birthday, traditionally known as "kanreki" in Japan.

"Kanreki in present-day Japan is 80 years old," Miura stated.
