Part 2&3  Someone you have helped to become healthier答案及解析_雅思口语练习「新东方雅思官方网校」

I think older people usually pay more attention to their health because they’re more likely to experience health problems as they age. They may care more about things like diet, exercise and regular check-ups. Young people, on the other hand, often feel healthy and may not think about these things as much. Of course, some young people are very health-conscious nowadays, especially when it comes to fitness, but overall I’d say older people are usually more careful.

Stress can affect both physical and mental health. If someone feels stressed for a long time, they may have trouble sleeping, lose their appetite or feel tired all the time. It can also make it harder to concentrate and may even affect their mood. I think a little stress can sometimes help people stay focused, but too much of it is definitely unhealthy. So people need to find ways to relax, like exercising, resting or spending time with friends.

I think it's mainly because they feel invincible at that age, you know? Nothing's gone wrong yet, so it's hard to imagine it ever will. There's also just a lot going on — studying, work, socializing — and sleep or exercise is usually the first thing to go. And honestly, staying up late and eating junk food is kind of normal in that stage of life. Most people only start caring once something actually starts bothering them.
