How are we defining "New Age superstition"?
The whole kit, from alternative medicine (homeopathy, acupuncture, non-FDA approved herbal treatments) to astrology to Western-friendly bastardizations of Hinduism (especially the yoga movement) and Buddhism to NeoPaganism right down to every quack Tarot reader and "Gypsy" fortune teller.
Don't disregard alternative medicine so fast. Even western doctors and pharmacists will admit western medicine usually just alleviates symptoms and doesn't really cure it and definitely doesn't prevent it. These herbal treatments certainly do work just as well as any western medicine considering you know what you are doing. We learned about them in Pharmacology and treated them like any other medicine. Of course even most western medicines are herbal extracts. If you are having a heart attack then feel free to pop some aspirin, but if you want to prevent it then look to "alternative" medicine.
I also don't see what's so wrong with people doing yoga. If they get all mystical about that sh**t then I admit its weird, but at the end of the day it's just another way to get your daily exercise.
