response: Interesting. Did you know that during running there is a phase when all feet don't touch the ground?
original_response: Really? I've been looking to get my feet above the ground. What time do you go in mornings?
history: Every morning I get up and go for a run. It's a great way to start the day.
knowledge: Running is a type of gait characterized by an aerial phase in which all feet are above the ground (though there are exceptions).
