Break a sweat
For some people, the natural high is just that: high up.
"Hiking and climbing mountains is better than sex," says Ramani Durvasula, a professor at California State University Los Angeles who discovered the sport last year after reaching a big weight loss goal.
"When you pull yourself up onto a summit -- and climax, so to speak, particularly as a woman -- the sheer physicality, beauty and endurance are like no other feeling on earth," she explains.
Durvasula, 42, has climbed summits throughout California. "My favorite 'lover' was Half Dome," she says, "the iconic rock formation in Yosemite." When she reached the top, "I fell to my knees. It was one of the best moments of my life."
