A retired school-teacher with multiple sclerosis has now climbed the tallest mountains on each of the seven continents. A dispatch from the expedition company Alpine Ascents International reported that Lori Schneider reached the 29,035-foot (8,850-meter)-high peak of Mount Everest on Friday evening. It's the tallest point in the world. The 52-year-old from northwestern Wisconsin climbed six of the other peaks, including Mount Kilimanjaro and Mount McKinley, after being diagnosed with multiple sclerosis in 1999. Schneider is reported to be the first woman afflicted with the neurological disease to reach the Everest summit and the first person with Mississippi to complete the Seven Summits.
