I don't think that primitive peoples are reliable reporters of their ages. I think their conceptions of age and accuracy of data are quite unlike the west. As for this doctor's comments about "ACCESS" to diverse foods, i think that's an unfortunate, communist word. I don't have "access" to someone else's home, food, property, life, body, wife, ad infinitum, NOR AM I ENTITLED TO SUCH ACCESS. She implies that postive rights are valid. Only negative rights are rights. I have no rights to access to resources that require provision by another person, or their efforts.
