As I age, and as I watch my mother age, I have become aware, sometimes painfully, that parts of the human body wear out or do not function as well as they used to. But I have also noticed that one part seems to retain its ability to function, but for many this part will need assistance from artificial devices. Someday, if you find yourself complaining about this or that part of your body not working, or not working like it used to, remember this: even if you are complaining through dentures or implants, you mouth still works!!!
If you can complain, you can also laugh and sing. Which is better?
