Life expectancy is lower as they follow more animalistic traditions and do not value modern medicine. Standard of living may be considered to the western world as poor. To them, its normal and adventurous (they do not sit inside all day, lol) Literacy is poor according to the western world, as they do not have a developed system of education. Income is little to none, as they do not value the same system of currency as we do. Mostly they trade and barter. Hope this helps!
