If you’re not dead, you’re not done. In the Bible, age is never a reason for someone to say no when God says go. Moses is eighty years old when God calls him to go to Pharaoh and lead the children of Israel out of Egypt. The Exodus starts when he’s eighty. Caleb is eighty when he asks God to give him one more mountain to take in the Promised Land.

Florence Detlor, a woman at the church where I work, decided a few years ago that she needed a new challenge, so she went on Facebook.

She was 101 years old at the time.

It turns out that out of the one billion or so people who were on Facebook, Florence Detlor was the oldest. In fact, when Mark Zuckerberg found out, he invited Florence Detlor from our church to go to Facebook headquarters on a personal tour and have her picture taken with him and Sheryl Sandberg.

When the first television interview went public, in a single day Florence got seven thousand friend requests. Seven thousand people from around the world said, “Florence, would you be my friend?” She says she’s getting carpal tunnel syndrome trying to respond to requests for her friendship —at the age of 101. If you’re not dead, you’re not done.
