        @calestous Your priorities are wrong, professor. What we really need to invest in is the integrity of the vote count.

        @gouaf At least read my article before you judge me. Review global trends since I wrote the article.

        Since when is adapting to the bell curve a good thing? It has wreaked havoc upon education systems. Expanding participation? Expand wisdom.

        False analogy aimed at demonizing the expansion of democratic space

        Democratic spirit is not an end in itself, it is a tool to be used prudently for the benefit of the society and its members.

        @AUC_DPA That is the most ridicilous idea ever. Voting should be only for people 40+, only then they have the wisdom.

        from that age and above mean, and of course there are exceptions, but majority of youth lack the wisdom.

        Considering majority of UK youth wanted access to 27 EU countries & stay in EU..I think all young should have representation

        @calestous #Africa should also lower age to be president or high government official. But not enough. Too much fraud & corruption! #Gabon

        Prof @calestous even when it's lowered to 10 years, a mere ballot paper can't bring any change in most #African Countries.
