Does sensitivity differ depending on age and health?

• A. No
• B. Yes
• C. It depends on the individual
• D. Not enough information

Answer: (B)

Sensitivity to environmental exposures changes with age and health status because our physiology, metabolism, and organ function evolve over life and are affected by disease. Children often experience higher exposure per body weight and have developing systems that can be more easily harmed by toxins, making them more vulnerable. Older adults may have reduced detoxification capacity, multiple chronic conditions, and medications that interact with exposures, increasing risk. People with preexisting conditions such as asthma, COPD, heart disease, or kidney/liver impairment may respond more strongly to pollutants or chemicals due to compromised clearance and altered physiology. So, it does differ depending on age and health.

The other options don’t fit as well: saying there’s no difference ignores well-established developmental and health-related changes; saying there isn’t enough information ignores the clear, well-supported pattern of differential susceptibility; and while individual variation exists, age and health reliably modulate sensitivity in a way that the general statement “Yes” captures.
