Purpose
There are many reasons why people swim, from swimming as a recreational pursuit to swimming as a necessary part of a job or other activity. Some people may also be forced in to swimming involuntarily as a result of falling into water.
The largest reason for people swimming is as a recreation activity, with swimming consistently ranking as one of the physical activities people are most likely to take part in. Recreational swimming can be used for people to exercise, to relax or to rehabilitate. The support of the water, and the reduction in impact, makes swimming accessible for people who are unable to undertake activities such as running.
Swimming is primarily an aerobic exercise due to the long exercise time, requiring a constant oxygen supply to the muscles, except for short sprints where the muscles work anaerobically. As with most aerobic exercise, swimming is believed to reduce the harmful effects of stress. Swimming can also improve posture.

Famous quotes containing the word purpose:
“The chief want, in every State that I have been into, was a high and earnest purpose in its inhabitants. This alone draws out “the great resources” of Nature, and at last taxes her beyond her resources; for man naturally dies out of her.”
—Henry David Thoreau (1817–1862)
“I envy neither the heart nor the head of any legislator who has been born to an inheritance of privileges, who has behind him ages of education, dominion, civilization, and Christianity, if he stands opposed to the passage of a national education bill, whose purpose is to secure education to the children of those who were born under the shadow of institutions which made it a crime to read.”
—Frances Ellen Watkins Harper (1825–1911)
“I have sought his aid—but if after endeavoring to do my best in the light which he affords me, I find my efforts fail, I must believe that for some purpose unknown to me, He wills it otherwise.”
—Abraham Lincoln (1809–1865)
