I’ve been saying that each country should disenfranchise the elderly by the national average life expectancy minus the same number of years you have to be to register to vote. We accept that young people aren’t fully developed and shouldn’t be allowed to participate until they reach a minimum age. Time to do the same with people who are at higher risk of dementia and who won’t have to live with the consequences of long-term changes.

I realize that this will unfairly disenfranchise able-minded people. They still shouldn’t get a say in our long-term future.
