Pictured is my 90-year-old grandmother after her first-ever yoga class with Lisa Boudreau last year. Though my grandma has always been nice and never crotchety, she's also Christian and has no idea what chanting is. She practices yoga almost everyday now at home and says yoga has helped her lower back (she has degenerating discs) and her legs. Restorative is more her pace and she loves Reclining Goddess pose:)
"When you do yoga, you start to become a nice person. Less crotchety."
Namaste to that!
