An autoimmune disorder, rheumatoid arthritis occurs when your immune system mistakenly attacks your own body's tissues. Unlike the wear-and-tear damage of osteoarthritis, rheumatoid arthritis affects the lining of your joints, causing a painful swelling that can eventually result in bone erosion and joint deformity. The inflammation associated with rheumatoid arthritis is what can damage other parts of the body as well.
Slavery in ancient Rome played an important role in society and the economy. Besides manual labor, slaves performed many domestic services, and might be employed at highly skilled jobs and professions.Teachers, accountants, and physicians were often slaves.Greek slaves in particular might be highly educated.uring the Pax Romana of the early Roman Empire (1stâ2nd century CE), emphasis was placed on maintaining stability, and the lack of new territorial conquests dried up this supply line of human trafficking. To maintain an enslaved work force, increased legal restrictions on freeing slaves were put into place.
Such institutions were a mixture of debt-slavery, punishment for crime, the enslavement of prisoners of war, child abandonment, and the birth of slave children to slaves. In the Roman Empire, probably over 25% of the empire's population, and 30 to 40% of the population of Italy was enslaved.
