### Instruction: What is a sedentary way of living?
### Response: When we talk about sedentarism in a community, we're talking about a group of people who settle down in one place and build their economic, social, and cultural lives there. The change from being nomadic to staying in one place is what led to the first civilizations. When we say that someone has a sedentary lifestyle, we mean that they sit or lie down for a long time and don't move around much or at all.
