Margaret Payne scaled Scotland's Suilven Mountain when she was 15 years old, and now at 90, she climbed the equivalent 2,398 feet without having to leave her home. Payne lives in Sutherland, Scotland, and while quarantined, she has been getting exercise by climbing her stairs. Inspired by Captain Tom Moore, the World War Two vet who raised tens of millions of dollars for the National Health Service by walking 100 laps in his yard ahead of his 100th birthday, Payne decided to turn her daily trek into a fundraiser. She calculated that if she climbed up her stairs 282 times, it would be the same as if she reached the peak of Suilven. It took 73 days, but she hit her goal Tuesday, raising $521,000 for the NHS and three other charities in honor of the care her husband Jim received before he passed away last year.
