Healing touch

Each Wednesday evening, I volunteer at Central City Co-op. CCC is a twice-weekly organic fruit and vegetable co-op here in Houston.
When I volunteer, I usually help a few customers, but most of my shift is "after-hours" as the co-op is packed away into a tiny, chilled room in the back of its venue. It is when I am crating and stacking away all the produce that I reap the non-nutritional benefit of my volunteer shift. Playing with the veggies has become a weekly cleansing ritual for me. I find the calm it provides me very mysterious. No matter how tired I feel, those fruits and veggies rejuvinate me. I know that if I were tempted to take a nap rather than head over to see the veggies (and fellow volunteers), I would be making the biggest mistake of my week. The co-op needs me, but more importantly, I need the co-op.

I am interested in information linking mood and the handling of fruit and vegetables. Tell me what you know.
