In my country, when you first take the driving license (so at 18 years old) you need to get an health certificate that states that you don't have any health issues like heart/epilepsy/diabetes/sleep apnea and everything that could let you suddenly faint during driving. Good idea, right? But that certificate is never asked again in the driver's life. Every ten years do a vision test and that's it.
Because you know, since at 18 someone is healthy, it means at 60 will be still perfectly healthy. No heart issues, sleep apnea or diabetes can develop after someone is 18....
