For the last 2 years I have been driving again after my stroke. It is not as easy. I'd say it feels like 5x the effort it once was. Driving at night is too stressful. I am tired/exhausted after driving.
I am aware I drive slower: it is as if everything is 10mph faster than it was. When doing 40mph it feels like 50mph and 60mph feels like 70mph.
Probably this is a combination of my brain and getting older.
