based on this chapter and the way the receiver lives, what's different about his lifestyle in comparison to the people in jonas's town?

I don't know what chapter you're looking at for this question, but the Giver's life is far different than that of any other member in the community. The giver cannot share his day or his work, he lives separate from his family, he experiences the worry, sadness, and fear that come with knowing things withheld from everyone else. The Giver lives in a world of isolation.
