Evidence indicates that those who volunteer at an earlier stage are less likely to suffer from ill health later in life . . . . For example: Data from interviews conducted in 1956 and 1986 of a group of women in an upstate New York community found that those women who had volunteered on an intermittent basis from the time that they married until the age of 55 scored higher on functional ability in 1986 than those who had not . . . . At the same time, a negative relation was found between health and paid work and caregiving. The researchers for this study posit that these outcomes may be due to the degree of autonomy that the women had in engaging in different activities: while volunteering was typically a discretionary activity, caregiving and paid employment were generally required of them.
