All of the listed conditions could potentially influence a person to become a nomad, but the most relevant ones would likely be:
-
Scarcity of resources needed for life - This is a fundamental reason for many nomadic lifestyles, as individuals or groups may move in search of food, water, shelter, or other resources.
-
A desire to live in a different area - This reflects the psychological or personal motivation to explore new places, cultures, or lifestyles, leading to a nomadic existence.
While the need for human company and dislike of neighbors might have varying influences depending on the individual's circumstances, they are less directly associated with the traditional reasons for adopting a nomadic lifestyle.
