This week I have been reminded of the fragility of life. None of us really knows what tomorrow will bring.

Certainly that is true for two people I know. One has just learned that her son - a young twenty-something, has an aggressive form of leukemia. With a young family of his own, he has a tough battle ahead of him. And as a parent, my thoughts are with his parents, because we just never want anything bad to happen to our kids.

Then yesterday I woke to a call from a girlfriend whose sister had just been contacted and informed that they had a kidney for her. In other words, they were offering her a new lease on life if she was willing to grab it. And she did. They scurried through all the prep work and last night, she received a new kidney. Exciting and scary at the same time. The next few days will be crucial but what a brave, life-changing decision she made.

So as you go about your day, be grateful and say a few prayers for those whose lives have changed - for the better or worse, in the blink of a second.
