My life compares to a hunter-gather's lifestyle in the fact that we both gather food. A huge differentiating factor is that hunter-gatherers were a much larger group a long time ago, and I live in the 21st century. Since technology has come so far, modern humans don't need to hunt or gather as much to survive. However, some people still have gardens, go hunting, or pick fruits from trees to survive.
Another difference between my life and hunter-gatherer's lives is that hunter-gatherers did not stay in one place for long. Since they depended on flocks of animals, they had to keep moving to stay with any migration of the herd. However, since people don't depend on that too much today, we usually stay put more often. Some families keep cattle on their property to breed and butcher them, but people back then couldn't do that.
