Human: I'm going on a long car journey with my family and I've heard that it's a good idea to stop every few hours and stretch our legs. Is this true? Assistant: 
Yes, it is a good idea to take frequent breaks during long car trips. Stretching your legs can help relieve tension in your back, neck, and shoulders, which can be caused by sitting for long periods of time. It also helps you stay alert and focused throughout the trip.
