It is likely that many people in Iron Age Britain would have died from diseases as babies or children. Many of those people who survived to be adults rarely lived beyond the ages of 35-45. Only about a third of all adults lived longer. Studies of the bones of Iron Age people suggest that at least a quarter suffered from arthritis in their backs from an early age. This was probably due to the hard work needed on Iron Age farms. Some women also suffered arthritis in the leg joints caused by squatting for long periods.
