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 Omnibus
Had no real purpose till it got to us.
Never believe it.”
—Robert Frost (1874–1963)
“Let our hearts, as subtle masters do,
Stir up their servants to an act of rage
And after seem to chide ‘em. This shall make
Our purpose necessary, and not envious;
Which so appearing to the common eyes,
We shall be called purgers, not murderers.”
—William Shakespeare (1564–1616)
“The purpose of playing, whose end, both at the first and now,
was and is, to hold as ‘twere the mirror up to nature: to show
virtue her feature, scorn her own image, and the very age and
body of the time his form and pressure.”
—William Shakespeare (1564–1616)
