It’s dangerous to draw lines. Where should we draw the age line? 80? 70? 60? I know people in their 70s with better cognitive abilities than the average middle age person. In that case, let’s ask for cognitive tests to gain the right to vote! Unfortunately there will be people who will never be capable of passing the test even during their 20s or 30s. Those who cannot pass the test could be less capable thanks to the environment (poor neighborhoods, poor education, bad childhood, missing one or two parents, exposed to toxic chemicals during pregnancy) or simply less lucky in the genetic side. Are we ready to take away the right to vote from old people even if they are more capable than you and me? If not, are we ready to take away the right to vote from less privileged people?
