John, an African American student, has chosen to incorporate exercise into his daily routine to prevent health issues. Based exclusively on his ethnicity, what is the most likely basis for his decision?

Find explanation below.

Explanation:

Ethnicity is a term used to describe a group of people with shared characteristics like culture, place of origin, language, religion, beliefs, etc. African Americans are an ethnic group in the United States, falling into the category of Hispanics and Latinos. They have their roots in Africa.

Africans have been found to be predisposed to certain health problems most likely as a result of adaptations to the environment they lived in. For example, they have a higher ability to conserve salts in their bodies compared to whites and this factor predisposes them to diseases like high blood pressure.

This might be why John has chosen to incorporate exercise in his daily routine to prevent health issues such as this.
