 28 years. My name is Dr. Peter Munda. I'm a chiropractor in New York, Long Island. I've been taking Balance of Nature for 23 years. I love Balance of Nature, and this is definitely a product that I would recommend to other people, and I'll never stop taking it. How many 70-year-old pictures you know? As far as Balance of Nature goes, I'll keep taking this stuff until the day I die, you know?
