Wait a minute... In the Americas, once you get your driving license you keep it forever? No retesting of any kind?? No health checks?
Here you need to go to special centers where they check your eyesight, coordination, etc to make sure you can drive safely. You need to do that again every time you want to renew your license, which at first needs to be done every 10 years, at some age it's every 5 years and then (I think) every year. Does this exist in the US of A and Canada?
