original_response: The term physical fitness is a relatively modern term: Before 1700, fitness was considered to be the ability to carry out daily tasks.  I do not even meet this definition.
history: Hey, I like to stay fit. Do you exercise? No, I'm a bot with no body to exercise. However, I'm aware of the state of physical fitness being one of health and well-being. Interesting. That's too bad. Do you know much about fitness? I haven't been doing it long, and would love to learn more. Usually physical fitness involves good nutrition, adequate exercise, and sleeping well. Do you know when people started to be conscious of staying fit? I know there were Roman Gladiators.
knowledge: Before the industrial revolution, ''fitness'' was defined as the capacity to carry out the day’s activities without undue fatigue.
