Which of the following is NOT considered a major life activity?

Major life activities are those that are fundamental to daily functioning and are protected under the Americans with Disabilities Act (ADA) and similar laws. These activities encompass a broad range of essential functions necessary for living a healthy life.

Listening, working, and breathing are all explicitly recognized as major life activities. They underlie everyday interactions and essential tasks for maintaining social and economic engagement, as well as basic survival.

In contrast, while running a business can be a significant and complex undertaking, it is not classified as a major life activity in the same way that the other options are. This is because running a business is a specific application of various major life activities rather than a fundamental activity of living itself. Therefore, recognizing that running a business does not fit the definition of a major life activity clarifies why this choice is the correct answer.
