Luma founder Erin Renny on yoga and longevity: "I won't promise you'll live longer with yoga. No one can promise that. But your life will be healthier, less stressful, and more physically in tune when you focus on connecting your mind and body or a regular basis. Yoga is my favorite way to express this connection. I want to share the secrets of lifelong yoga with anyone willing to breathe and learn with me."
