Aluminium corrosion resistance. Aluminium corrosion resistance is very good in untreated aluminium. Untreated aluminium has very good corrosion resistance in most environments. This is primarily because aluminium spontaneously forms a thin but effective oxide layer that prevents further oxidation.
Human body is just the medium for soul to survive on earth. Soul wears human body for its learning on earth. Soul can not experience feelings in its original form and therefore it needs a human body. Now when a human body dies, a soul leaves that body and return to its original form. Sometimes, in case of sudden accident, a person dies and soul returns to its original form.
At the same time, without circulation to keep it moving through the body, blood starts to pool and settle. Rigor mortis, or a stiffening of the body, sets in about two to six hours after death [source: Marchant, Middleton ]. While the body as a whole may be dead, little things within the body are still alive. Skin cells, for example, can be viably harvested for up to 24 hours after death [source: Mims ]. But some things that are still alive lead to the putrefaction, or decomposition, of the body -- we're talking about little organisms that live in the intestines.
