 When Diane Van Deren was in her 20s, the epilepsy that she experienced as a child came back with a vengeance. Though she tried various treatments and interventions, she found only one thing stopped the seizures…running. Whenever she felt the sense that a seizure was coming on, she'd lace up her shoes and take off for a long-distance run through the national park near her house. Diane had brain surgery to remove a golf ball-sized portion of her brain, which left her entirely seizure-free. However, she no longer has any short-term memory, but there's an upside. In distance running, where obstacles are both physiological and psychological, having no short-term memory is a gift. Because she has always focused on the present moment, Diane is never dragged down by the thoughts about where she is, how far she's come, or where she's going. She can run farther and longer than anyone because she has a superpower that very few have. She's always focused on the present moment.
