Thie TripAdvisor Forum thread at the link below is 2 years old but I'm posting it because it is another example of insurance companies limiting the activities of the older individuals specifically by setting a maximum age limit.
The OP wanted to rent a car on Grand Cayman and the rental agency agreed to rent the car - but they refused to sell him any liability insurance because he was 75 years old.
It turns out that age limitations/polices for car rentals may vary by agency in Cayman - and perhaps also in other areas of the world?
