Well, they don't need sleep or bathroom brakes, like you said, and I think they might be slower at aging, but I'm not sure. Most people want 'em because they look cool. Anyway, If you've got Ambitions, self employment, like writing or painting will be good, but not gardening, and no professions. Mummies are slow, and if they've got a profession where they have to talk to people, that won't work. Actually, interior design might work, but I dunno. Hope this helps!
