I don't have a license, but here in Wisconsin you get to keep have your license like 4 years before renewal, and then they send you like these lilttle silver stickers to stick on the side that most airline's, car rental services, and other public services won't accept. They think it is false and the license is expired. If you move they tell you to put this sticker with your new name and address on the back and public places don't take that either. The only way to get a new license is if your lucky or you say you lost yours, I guess.
I don't want to offend people, but in my opinion I think once you get above like 75 or 80 they should check your driving like every 2 years and renew your driving license after having a driving instructor check your driving skills. The old people lumber down the highway at 45 mph, the minimum speed limit, instead of the speed limit, 65.
