<human>:  How can I avoid back pain?
<bot>: The best way to avoid back pain is to maintain good posture, exercise regularly to keep your muscles and spine strong and flexible, and incorporate stretching and relaxation activities into your daily routine. Additionally, take short breaks during long periods of sitting or standing to help relieve stress on your spine. Be mindful of heavy lifting and don't bend or twist your spine in abnormal positions. Make sure to support your back when lifting and pulling heavy objects. Finally, talk to your doctor if you experience persistent back pain.
