I don't think it's age-related. I have been clumsy since I was a toddler and am now a clumsy 29-year-old. I'm willing to try just about anything that might help as long as it isn't potentially harmful.
I think 16 years of dance class helped when I was a child/teenager but there's not much opportunity for that kind of thing as an adult unless one is doing it in a professional capacity. I don't think my occasional sashaying down the aisles at work counts as professional dancing.
