input: Death by natural causes

A death by natural causes, as recorded by coroners and on death certificates and associated documents, is the end result of an illness or an internal malfunction of the body not directly caused by external forces, typically due to old age. This is especially true when an elderly person has several different conditions or diseases, but where it appears that none of them alone or together may clearly lead to the death, and it is uncertain which condition was the final factor causing death. Contrary to the statement before, everything is natural at some point. For example, a person dying from complications from influenza (an infection) or a heart attack (an internal body malfunction) or sudden heart failure would be listed as having died from natural causes. Health departments discourage listing old age as the cause of death because doing so does not benefit public health or medical research. Old age is not a scientifically recognized cause of death; there is always a more direct cause, although it may be unknown in certain cases and could be one of a number of aging-associated diseases.

input: List of national identity card policies by country

Regional government issued driver's licenses and other cards indicating certain permissions are not counted here as national identity cards. So for example, by this criterion, the United States drivers license is excluded, as these are local (state) government issued (although these or the state ID are all-but required as nation-wide identification).

input: Eastern green mamba

This species is indigenous to more coastal regions of southern Africa and east Africa. The eastern green mamba's range extends from Kenya south through Tanzania, Mozambique, Malawi, eastern Zimbabwe, eastern Zambia into South Africa as far as southern Natal and northern Pondoland. It can also be found in Zanzibar. The distribution of this species is assumed to be continuous, but reports seem to be scarce in regions within the species' range.
