What are two ways of how the lives of people were affected by having to be hunters-gatherers?

As hunters and gatherers, people had to constantly search for food, which led to a nomadic lifestyle as they followed animal migrations and seasonal changes. This lifestyle meant they had to be constantly on the move, without the security of permanent settlements. Additionally, the reliance on hunting and gathering meant their food sources were not always predictable, leading to periods of scarcity and famine.
