My 95-year-old mom was reminiscing yesterday about climbing Half Dome in Yosemite–twice–in her 70s! She has been exercising every day since she was in her 30s, but she didn’t start hiking until she was in her late 50s. The first time she hiked with the Sierra Club, she says she had difficulty getting up the incline out of the parking lot. It’s never too late to start. And look where it can get you!
