If you become a centenarian, you can take up smoking without worrying about the long-term effects!

On the day a good friend turned 96, I chanted, "Four more years! Four more years!"

She shook her head and smiled bemusedly. "Oh, Randy, there are a few days when I'd like to, but mostly, I'm ready to go."

While I've long had an unspoken goal to live to be 100, I will not fully commit to it until I'm 96. At that point, I should have enough experience to make an informed decision.
