Last time I renewed my license I paid a little extra and had it renewed for 10 years. It won't expire till 2018.
But.....I hardly ever drive anymore. To the grocery store, drug store and doctor is about the only place I go (alone) anymore.
I won't drive if I'm having issues with my vision. I wouldn't want anyone else to endanger me so I won't endanger them. Just wish everyone thought along the same lines as this.

I see so many people on the road who obviously don't belong there.
