Going outdoors and taking on new challenges makes you healthier, happier and smarter. Spending time in nature away from cities and suburbs can also bring spiritual and emotional benefits.

Co-host Jim Meigs tells us why he's a big outdoor guy, who loves to hike, bike and head for the hills.

In this episode we look at ways to add adventure to your life and embrace the excitement of leaving your comfort zone. 

Kio Stark, author of "When Strangers Meet: How People You Don't Know Can Transform You," explains why meeting people you don't know can have genuine emotional benefits. Even brief chance encounters, she says, can make a difference to how you view the world. 

We also discuss cycling in cities with Nicole Gelinas of The Manhattan Institute. She tells us about ways to improve urban safety for bikers, pedestrians and motorists.
