TheGift

Raised in the Christian faith I was often reminded that "my life is God's gift to me; what I do with my life is my gift to God." 

Regardless of our spiritual or religious inclinations, we can all probably agree that our lives are a gift.  Beyond that, our bodies and minds (and spirits, if you're so inclined) are fundamental to that gift of life.  There seems an aspect of stewardship that is tightly tethered thereto.

If you can accept the obligation component of my first sentence above (the part after the semicolon), then...
how we treat and relate to others,
          how we spend our time,
                    what we choose to read/view/listen to,
                              how we nurture our bodies,
                                        to what causes we lend our talent,
                                                  the degree to which we attend to our wellness,

have EVERYTHING to do with our giving back.  

It's a debt owed, and one we can surely attempt to repay.
