Buster Martin is 101 years old. But don't go judging that number - Buster just completed a half marathon (that's 13.1 miles)! He also still holds a job as a van cleaner, is a member of rock band The Zimmers (which is composed of some of the oldest people still alive today), and writes a regular advice column to younger generations in For Him Magazine. Next up on Buster's to-do list: the London Marathon! 26 miles!
Check him out in the news. And on YouTube (this will amaze you and make you laugh).
