In medieval times, if someone displayed the symptoms we now identify as boredom, that person was thought to be committing something called acedia, a 'dangerous form of spiritual alienation' -- a devaluing of the world and its creator.

This seems clear enough: When truly present in nature, we do use all our senses at the same time, which is the optimum state of learning.

Children who played outside every day, regrdless of weather, had better motor coordination and more ability to concentrate.

Time in nature is not leisure time; it's an essential investment in our chidlren's health (and also, by the way, in our own).

Nature introduces children to the idea—to the knowing—that they are not alone in this world, and that realities and dimensions exist alongside their own.

Use all of your senses.

Nature is one of the best antidotes to fear.
