Why isn't it not a surprise that Janet is always adding dates to her tours? She is a very engaging performer, and can perform for the rest of her life if she chooses to. 'Rhythm Nation' could be 50-years-old and people will still fork out to see Janet perform. That's the beauty of having an iconic back catalog full of classics. Janet can ride that album until the wheels come right off. Her recently wrapped Vegas residency was also a huge success.
