Born in Den Haag in the Netherlands, Gerardus Jacobus Johannes Keizen enjoyed the attention of being photographed, says Thormaehlen. Keizen tugged at his hair and twirled his mustache as he prepared to pose. His secret for living so long? A routine life of moderation. Go to bed early, don't smoke, don't drink — although you can always make an exception now and then for a whisky. And for gin, too.
