It’s the perfect exercise for fighting fat – as well as fatigue and stress. Here’s how to do it right.
Though you may not think of walking as a wonderful form of exercise, it is. Walking promotes cardiovascular fitness, tones up all your muscles and is a great fat burner too. If you walk briskly for 45 minutes a day, by the end of a year you’ll have lost more than 20 pounds, without dieting! So imagine what walking does when you do diet. Since your metabolism speeds up, weight comes off faster and tends to stay off.
Some other advantages of walking: it requires no special skills or equipment, it can be done almost anywhere at any time, and it’s virtually injury-free, provided you wear proper shoes, start off slowly and don’t overdo in the beginning.

What makes one out-of-control teen-ager grow up to live a normal life while another turns to murder?
A growing body of research suggests the answer may lie in a part of the brain that controls planning, reasoning and impulse control. Studies are revealing physiological differences between the brains of normal people and those of people who kill.
“There is clearly a biological predisposition to violence”, says psychologist Adrian Raine of the University of Southern California. “We know there are murderers who don’t have the usual signs – a history of child abuse, poverty, domestic violence, broken homes – and yet they commit violence. Research suggests the cause may lie internally, in terms of abnormal biological functioning.”
Raine led studies comparing the brains of 41 murderers with those of 41 nonviolent people matched by age and gender. He found that “murderers” have poorer functioning of the prefrontal cortex, the part of the brain that sits above eyes, behind the forehead. It’s a part of the brain that controls regulating behaviors – the part that says ‘wait a minute’.”
In another study, Raine divided the murderers in two groups: those from healthy, stable family backgrounds and those from abusive, dysfunctional homes. “It’s the murderers from the good home environment who have the poorest brain functioning,” he says.
