Hello how may I help you? Hi, I'd like some information about world records I can help you with that. What record would you like to know about? Who is the world's tallest man? Currently living or of all time? Both, why not The current tallest man alive is Yao Ming, while the tallest man ever was Hector Johnson How tall were/are they both, respectively? Yao is 9' 6", and Hector was 9' 11" Interesting, thanks for the information Is there anything else? Nope, that'll be all
