According to National Geographic writer and bestselling author Dan Buetter, gardening can actually  help you live longer!  His studies found that people living in Blue Zone communities (areas in which people live longer) practice continual light exercise, such as gardening.  Gardeners not only benefit from the daily exercise, they get daily exposure to sunshine which is a great source of vitamin D, and they typically eat lots of fresh veggies.
