     Walking is a great way to get in shape without breaking the bank (it's free and you do it every day).

It benefits people physically, psychologically and socially. Here are how:

    Keeps You in Good Health

     In terms of health, walking is the key to managing weight, controlling blood pressure, and reducing the

risk of a stroke, breast cancer, and many other illnesses. A quick and energetic daily walk lengthens your

life, decreases the risk of disappointment and keeps up your mood and sense of wellbeing.

    Keeps You Mentally Refreshed

    From a psychological viewpoint, walking offers an opportunity to clarify thoughts, to solve problems

and to reduce stress. If you take a walk that is relaxing and peaceful, walking can also become a form of

meditation(冥想).

     Allows for Social Relationship

     Walking regularly with someone else enables a friendship to develop as the pair of you exercise.You

can also schedule regular walk "dates" with your partner and use the time to discuss questions without

being disturbed.

     Lets You See the World Around You

     Also, the best way to explore some of the world's great cities-such as New York, London, Paris and

Rome-is on foot. Walking motivates the senses and enables you to enjoy a rich life around you.

Wordsworth, who is believed to have travelled around the world seven times during his lifetime, always

delighted in the truth that "going for a walk is an invitation for surprise".

    Here are some tips to get going:

    Get a walking partner and meet each week at a set time.

    Get a dog and you'll have a constant walking companion.

    Choose a spot that is charming but accessible.

   Start with a soft walk, then increase the pace and distance.

   Include some hills and stairs.

    Use an umbrella if it rains: the worst that can happen is that you get wet!
