Final answer:
Based on the information provided, middle-aged individuals, particularly college graduates with full-time employment, may experience more overload stressors that involve juggling too many activities at once, such as social responsibilities, kids, and parents.
Step-by-step explanation:
The age at which people experience more overload stressors that involve juggling too many activities at once, such as social responsibilities, kids, and parents, can vary. However, based on the provided information, it can be inferred that individuals in their middle-age may experience more overload stressors.
According to Figure 14.6, stress levels among different demographic groups were surveyed in 1983, 2006, and 2009. From 2006 to 2009, the greatest increase in stress levels occurred among college graduates and those with full-time employment. This indicates that individuals in their middle-age, who are more likely to have established careers, may experience more overload stressors.
Additionally, the information mentions that women often have greater responsibility for family demands, including child care and caring for aging parents. This suggests that individuals who are balancing multiple roles, such as parenting, work, and caring for parents, may experience more overload stressors.
