Just like 16 years old people can’t vote because too young, 80+ years old people should not be able to vote, most of them are too distant from everyday reality of younger people to be able to take a wise decision for the community and also often stick with (way too) old ideals from their years
I think the average life expectancy age is a good point. It would encourage people to work to increase life expectancy because it widens the voter base. It would mirror the exclusion of younger peoplefrom the voting process too.
