Should we include an equivalent analysis of the declines in cognitive function after 70. In my experience they are much more marked than any deficits teenagers may have.
Why not go further and also consider the cognitive implications of being ill, depressed, obese, stressed, parent of a newborn, or any other condition that could have short or long term implications on mental sharpness?
I really hate when these ideas come of that effectively boil down to creating some kind of litmus test for who can be "trusted" to vote. We have an age limit, maybe the UK wants a lower limit, but at least that's a pretty simple and clear line to be drawn.
It's important to note the current discourse that Biden (82) is far too old and in a cognitive decline, while Trump (79) has a state of health that is beyond question.
