If you're planning on climbing Mt. Everest any time soon (and let's face it, I wasn't) you might want to get around to it sooner than later. A recent study found that climbers over the age of 60 are three times as likely to die on the mountain that younger climbers, and are also less likely to reach the top. Climbers are apparently getting older, and experience is important when climbing a mountain, but age means you're less physically fit and more likely to fall. In fact, for older climbers, descending the mountain is the most dangerous part.

Though the study didn't include other mountains, I have to imagine that this hold true no matter what peak you're trying to bag. If you're a climber in your upper decades, good for you! And take extra care while you're out there!
