I was given my key by a wonderful friend who has always been inspiring to me. She gave it to me at a time when I really needed it, and it arrived at the time of my Grandmother's death. I have been wearing it for over 6 months now. Although I feel like I could wear it forever, I am giving it away to one of my best friends that I have known for almost 30 years. Unfortunately, her mom was in a horrible traffic accident and is in ICU currently. I feel that she can definitely use the "STRENGTH" key now more than ever.
