YOUR FACE receives more blood flow, so your__skin__glows more and wrinkle 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 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.
