With our already busy lives, finding time to exercise can be impossible. So maybe it would help if there was ‘a best time' to exercise.

There are clear benefits to exercising in the morning. Many of us have more free time than later in the day, and it may be easier for us to keep a morning plan. A study found that people could sleep better when they exercised in the morning or had the physical activity during the whole day. Exercising on an empty stomach（空腹）before breakfast could also have less fat（脂肪）and keep healthier.

So, good news for early birds, but what if you're not a morning person? Working out in the afternoon or evening is also good, but different. For example, your body's ability reaches the highest level in the afternoon, according to a 2010 study. Also, in the afternoon and evening, your mind is the quickest, and your heart rate and blood（血）pressure are lowest, and you aren't getting hurt（受伤）easily when exercising.

But can this happen? Deciding on if you are a man or a woman? Our bodies are different, after all, so the best time to exercise may be different too. Want to reduce（降低）your blood pressure and you are a woman? Exercise in the morning. Want to improve your heart health and you are a man? Evening is better for you. But, a 2022 study found that it's both OK for them to exercise at either time of day.

So what time is best? It seems the answer is: whatever time is best for you!

Athletes from various countries displayed the charm of competition sports during Beijing Winter Olympics. One of the reasons why this Winter Olympics can be successfully held is the robots who work hard behind the scenes. 

In the dining hall, instead of human waiters, food arrives from the ceiling. To our surprise, the cooking robot can make delicious dishes according to the programs; food even like burgers are being prepared automatically. 

It doesn't stop there. Elsewhere in the media center, a robotic arm is serving up cocktails. It takes just 70-90 seconds to measure, shake and serve. 

Look at this robot. Although it is only 140 cm tall, it only takes one minute to sterilize（灭菌）36 square meters. The space even more than 1,000 square meters can be easily dealt by itself. The robot can hold 16 liters of disinfection（消毒）water at one time, and spray（喷雾）around through the small fan above its head.
