Last weekend, John was running in the middle of the park when he suddenly tripped over a large rock. He lost his balance and fell to the ground. (27) Soon after, the muscles in his leg became stiff, and his knee and ankle became very painful and swollen. He could not stand up, so a kind stranger helped him get to the hospital. At the hospital, a very patient doctor examined him carefully to see how bad the injury was. (28). He was just told to take some medicine and wrap the injured limb with a bandage. (29). In reality, he struggled to do this because he was an active person who hated staying indoors. This injury prevented him from exercising for a few weeks. During his recovery time, John noticed some negative changes in his body. (30). In response to this, he decided to take up a healthier diet with delicious food that suited his taste, hoping to fit into his old clothes again. Furthermore, he tried to sleep early instead of staying awake all night watching TV to de-stress. (31). Thanks to these healthy habits, he felt more alert, flexible, and full of contentment.
