Why a walk in the woods might save your life ... really

Spring has sprung and your local forest is stirring into life so what better time for a walk in the woods.

Still reluctant? Well, it turns out that walking in the woods is more than just a pleasant way to spend an hour or two - it might actually prolong your life.

The Japanese have a word for it: "shinrin-yoku" or forest bathing. It's the sensory experience of being among trees. It's a rich form of physically active mindfulness. Forest bathers are encouraged to put away their mobiles and their headphones, and instead activate all their senses to interact with the forest environment.
