Generate a series of (instruction, response) pairs that are similar in context and structure to the example provided below. Each pair should consist of a concise instruction followed by an appropriate, detailed response. The instruction should pose a clear task or question, while the response should provide a comprehensive answer or solution that could be understood by someone with a basic understanding of the subject.

Instruction: Please provide a brief summary of the text below:

Collin Sexton took his first steps toward basketball stardom on Thursday as one of the 69 participants at the 2018 NBA draft combine in Chicago. 

Sexton officially measured in at 6'1½" with shoes on and a 6'7¼" wingspan. The 19-year-old weighs 183 pounds and has 5.6 percent body fat on his frame, with hands that are 8½" wide and 8¼" long. 

Among pure point guards taking part in the combine, Sexton ranks fourth in wingspan and is tied with Devonte Graham and Jevon Carter for ninth in height with shoes on. 

ESPN's Jonathan Givony noted Sexton's height "ranks in the bottom 10 percent of all players ever measured at the combine, but his length sits a bit more favorably."

Other than measuring in, this was a fairly quiet day for Sexton in Chicago. He told reporters about meeting with the Chicago Bulls and New York Knicks. Both teams own top-10 picks.

Your task is to generate more pairs that maintain this level of clarity and detail. The topic is Summarization. Write a long text of instruction by yourself, then summarize the given instruction in a response. Ensure that the responses are informative and accurate, suitable for an educational context. 

Store the generated pairs in valid JSON format, with each pair as an object within an array. Each object should have two key-value pairs: "instruction" and "response". For instance: 

{"contents": [{"instruction": "text", "response": "text"}, {"instruction": "text", "response": "text"}, ...]} 

Remember to maintain consistency in the format and ensure the generated pairs are diverse and cover a broad range of subjects. You must return the response in the asked format and you must not add any additional text in your response.

Summarize the main points discussed in the following text about the importance of physical activity for mental health:

Regular physical activity has numerous benefits for mental health and well-being. Exercise releases endorphins, which are natural mood-boosters that can alleviate symptoms of depression and anxiety. It also reduces stress levels by lowering cortisol, the body's primary stress hormone. Additionally, physical activity promotes better sleep, which is essential for emotional regulation and cognitive functioning. Engaging in exercise can also boost self-esteem and body image, as well as provide a sense of accomplishment and distraction from negative thoughts. Furthermore, many forms of physical activity involve social interaction, which can combat loneliness and foster a sense of community. Overall, incorporating regular physical activity into one's lifestyle is a powerful tool for maintaining and improving mental health.
