No that should be private but if a politician is showing clear signs of incompetence they should be ousted.

 @BDXRQGLanswered…2wks2W

Yes, and I would prefer term limits to be imposed

 @BDTLJSZanswered…3wks3W

Yes, as long as it doesn't discrimate on the basis of age, so all politicians should pass it, we need experienced leaders, but it should be made as objective as possible so bias doesn't sneak in.

 @BD8L3C5answered…2mos2MO

Once they get to 80 it should be that they have to no longer be a member of Parliament. People are living and working a lot later in life these days.

 @BD39LT4answered…2mos2MO

No, only over the age of 85.

 @BCP5PGWanswered…2mos2MO

Yes, but make sure the testing process is fair and revised by multiple groups, who aren't backed by elites, every decade.

 @BCN9QKTfrom Ontario  answered…3mos3MO

No, I would prefer an age limit of 75 instead.
