"We should consider every day lost in which we have not danced at least once." Friedrich Nietzsche
If German philosophers aren't your thing, consider a University of London study which revealed that patients with anxiety disorders showed significant improvement when they participated in a modern dance class.
A study in the New England Journal of Medicine noted that dancing may boost memory and prevent dementia. The hippocampus (the part of the brain that controls memory) naturally shrinks as people grow older. Aerobic exercise (like dancing) can reverse volume loss in the hippocampus.
Plus dancing is a great way to meet people. Dancing attracts people of all ages from college to retirement from all walks of life. On the dance floor I've met architects, engineers, professional musicians even a doctor who kept her profession on the down low since she wanted to dance not diagnose on Friday nights at Salsa.
With one activity you can improve your memory, lose weight, reduce stress and meet interesting people. What are you waiting for?
