Question

Quizplus · Accepted Answer

People in low-status jobs are often subject to chronic stress, which can compromise their immune system and make them more vulnerable to respiratory infections. Teenagers in large high schools may also be at risk due to close proximity to others, but stress is not necessarily the primary cause. Elderly people living with their families may actually have stronger immune systems due to social support, and people who work in international jobs may face various health risks but not necessarily respiratory infections caused by stress.
