Research on Social Supports Indicates That

Research on social supports indicates that:

A) social support comforts lonely individuals dealing with stressful circumstances, but it does not affect the individual's immune system
B) firefighters' heart rates and cortisol levels return to normal more quickly through the mere presence of a reassuring friend.
C) older people who have cats as companions tend to visit medical clinics less often than their peers who have dogs.
D) truly loving family and friends provide social support and don't cause unhappiness, stress, and anger in the lives of their loved ones.
