90-year-old WWII veteran rappels down a skyscraper to raise money for cancer research

Richard Keller, a 90-year-old World War war veteran, added a new experience to his list while raising funds for cancer research.

CBS Philly reported that the senior daredevil rappelled down a skyscraper over the weekend in Denver. He said:

“It’s a wonderful thing to try. I encourage everybody to try it at least once in life.”

He had a crowd of approximately 160 spectators cheering him one as he slid down the 38 stories of the Hyatt Regency building.

The funds raised went towards the Cancer League of Colorda, a cause close to Keller's heart as he had battled prostate cancer previously.

He admits that it "took some daring" to get him interested in the day but he doesn't regret doing it and says he would do it again.

"You’ve got a throttle and a break, and your arms…they must be working in coordination which was type of difficult to get it good so I may maintain going."

Veterans are often forgotten by society, but Keller wants to make sure that he lives life to the fullest and make an impact while he's here.

Another war veteran who recently made headlines was the 36-year-old double Noah Galloway amputee soldier who served in Iraq.

Earlier this year, he stunned judges on Dancing With The Stars when he showed that physical limitation would not get in his way.

Galloway was teamed with Sharna Burgers and the performer to a fitting song: Toby Keith's "American Soldier."

They gave an energetic dance routine and the judges praised Galloway for his ability to inject emotions into his performance.

Apart from having a good time doing what he loves, Galloway also opened the debate around disabilities.

HIs goal is to highlight the misconceptions people might have. Read more about the extraordinary former soldier here.
