Dutch dressage rider Adelinde Cornelissen performs before winning the Grand Prix Special during the European Dressage Championships in Rotterdam.

Dressage is an Olympic sport that's been described as "ballet for horses." Riders, dressed formally in a top hat and tails, subtly lead their horse through a set of delicate motions, including pirouettes and deep bows. It's an expensive hobby, horses can cost more than $100,000 — and the price tag doesn't include feeding, training and veterenarian care.

But for Ann Romney, wife of presumptive presidential nominee Mitt Romney, it's been a life-line. Ann rode horses when she was younger, but started again when she was diagnosed with Multiple Sclerosis as a 50-year-old, and credits dressage for dealing with the disease.
