Read the rough-draft paragraph.

studies support the claim that volunteering on a regular basis actually benefits one’s general physical health. depending on the needs of an organization, many volunteer opportunities can involve physical movement. volunteers at a local soup kitchen may, for example, find themselves unloading truckloads of donated supplies. other research related to volunteering and staying healthy found that volunteers often experienced decreased chronic pain and fewer symptoms of heart disease. of course, not all volunteer positions involve physical exertion. tasks involving minimal movement, such as answering phones, filing papers, and/or addressing envelopes, should be combined with some type of physical activity. using the stairs instead of an elevator or walking to work instead of driving are examples of easy ways to integrate exercise into a daily routine.
