A dakhma (Persian: دخمه), otherwise referred to as Tower of Silence (Persian: برجِ خاموشان), is a circular, raised structure built by Zoroastrians for excarnation (that is, the exposure of human corpses to the elements with the purpose to enable their decomposition), in order to avoid contamination of the soil and other natural elements by the decomposing dead bodies.[1][2][3] Carrion birds, usually vultures and other scavengers, consume the flesh.[1][2] Skeletal remains are gathered into a central pit where further weathering and continued breakdown occurs.

This would be an OK way to go out. Too bad they don't do it any more.
