Hello how may I help you? I need some world record info please? Certainly. What world record information do you need? Who is the tallest person in the world? The tallest person in the world is Sultan Kosen. He stands 8'3" tall. Cool. Where does he live? Wait. did you mean the tallest living person or the one of all time? Because there is a difference between the two records. Tallest living person of all time? That would be Robert Pershing Wadlow. He was 8'11" Oh, ok great. Wow that is tall. Thanks for the info Anytime. Need help with any other record information?
