I think the lines "Take care of the old man, See if he's in pain, Have somebody stay with him, Comfort him when he complains" refer to a skeleton found in the Shanidar cave in what is now Iraq (http://en.wikipedia.org/wiki/Shanidar_Cave#Shanidar_1). It was a skeleton of a forty or fifty year old man, with severe disabilities, including a damaged eye, withered, largely useless right arm and numerous deformities on his legs and foot, which would likely have left him with a bad limp. He would have been useless to the tribe, but the injuries had healed years before death, showing the Neanderthals looked after their sick and aged.
