I believe this is a basic insight at the core of many aspects of human life. For example:

• Variety of diet
• Variety of physical positions/movement (i.e. Why you shouldn’t sit all day, or why it’s good to exercise)
• Variety of physical location (i.e. Why 100% remote work is difficult for many people)
• Variety of daily experience (i.e. Why people travel to other places for vacation)
• Variety of people to be around (i.e. Why people can get annoyed with each other if they’re constantly around each other too much – like families)
• Variety of daily occupation (i.e. Why people switch jobs every few years)
