True Meaning of "Quality of Life"

Many have heard the term "quality of life" before, especially with the case of Terry Schiavo. Some say that if you can't do anything anymore, then you don't have a "quality of life". I discovered the true meaning of "quality of life" when I met a single mother, who adopted a severely disabled & terminally ill child. People thought she was crazy since this requires tremendous sacrifice. But when asked why, she said no one else will want a child who can't do, nor become, anything. But she wants a child, not to get something back , but rather to give. So she adopted the child to give him love. That child died recently and the single mother grieved the loss. But she had no regrets. That's because that child received the most important thing of all - to be genuinely loved. Now that's what it means for both of them to have a "quality of life" - to be able to love and be loved.
