Being beaten by a grandma in hand-to-hand combat might sound embarrassing at first, but when this woman's the granny in question, you really just have to accept the fact that she's a champion.
Much to my delight, 76-year-old Meenakshi can do something that shocks people from near and far. As a master of the ancient Indian martial art form of Kalaripayattu, she's able to take down athletes half her age!
Once you see this woman in action, you'll make sure to steer clear of her if you ever visit India.
Today, Meenakshi teaches these techniques to 150 students in Vatakara, Kerala. However, she takes no money, and instead runs her class through donations. How amazing is that?
