My wife and I want to start taking Yoga classes. Is it ok to be taking Yoga classes at the age of 38? It would not be harmful to us right? What types of yoga exercises are best suited for an old couple, not that we think we are old? I am looking for someone in Brooklyn who is an excellent Yoga teacher or if there are Yoga classes held. Is it better doing it with other people around or should it just be me and my wife in the house? Is it safer to start with a professional or can Yoga be taught to yourself?
