Answer:
Differential susceptibility
Explanation:
<u>Differential suceptibility refers to the idea that people can react very differently to the generally expected outcome.</u> When it comes to health, lifestyle choices and living conditions aren't often enough to explain outcomes, as people are born with different susceptibility to different ailments. In this example, Aaron was born with a bigger susceptibility to diabetes. This meant that even though he led a healthier lifestyle, he still developed diabetes. Meanwhile, Clement had a natural resilience, so even though he didn't take care of himself, he didn't get diabetes.
