At 39, Allan Misner was well over 250 lbs. That was the last time, though. Over the next 8 months, Allan lost 66 lbs and capped off his weight loss journey by completing a Tough Mudder with his 21yo daughter. This tough motherfu**er went on to create a thriving 40+ fitness community and continues to share his fitness secrets with middle age messes all over the world.

Jennifer Cain Birkmose is unbelievable (albeit accessible at www.vivavalet.com). She went from navigating minefields in Bosnia to saving poor countries with the World Health Organization to (ugh!!!!) Big Pharma, and then put that all away to be an improv performer in Switzerland while she's revolutionizing the Senior Housing industry. It's quite an adventure and a simply fascinating story to hear.

David Petrovay spent more than two decades teaching and counseling blind students across the United States, although he'll tell you that these kids taught him a lot more than they learned. When he felt himself sliding into a Middle Age Mess, he transitioned into career counseling, published three books and now uses his lifetime of experiences working with some of the most inspirational children in the world to inspire and transform people's lives.
