Most people are known to take a very easy approach to life in their 90s, but one man is proving that age is literally just a number.
Meet Alan Still, who is 91 but more than happy to remain active and adventurous.
He's a literal daredevil in human form who considers himself young, even at this age. And he's proving that he's got what it takes, that people half his age would consider a mighty job. Think along the lines of skydiving at this age to raise funds for a charity.
Yes, his little deed helped in raising $5000 for a charity, but he's not ready to stop just yet. His next task is taking on the mighty challenge of completing a 100 mph zip line. While his family is skeptical about the ordeal, he says there's nothing that can stop him once he's made up his mind. Now that's what we call fearless.
