[社会生活型阅读理解(一)]
Life is to be enjoyed. There's no point in giving up something you enjoy unless yo u get something back that's even better. When people eat more healthfully, exercise, quit smoking, and manage stress better, they find that they feel so much better that it reconstructs the reason for making these changes from fear of dying to joy of living.

YOUR BRAIN receives more bloo d flow and oxygen, so you become smarter, think more clearly, have more energy, and need less sleep.

YOUR FACE receives more blood flow, so your_skin_glows more and wrinkles less. You look younger and more attractive. In contrast, an unhealthy diet, chronic emotional stress and smoking reduce blood flow to your face so you age more quickly. Smoking accelerates aging because nicotine causes your arteries (动脉) to narrow down, which decreases blood flow to your face and makes it wrinkle earlier. This is why smokers look years older than they really are.
