The world is increasingly becoming a more military place, it feels like we have entered a new modified cold war filled with groups who have no country and no flag. In the past couple of years it is has become clear that the strongest armies in the world are not the ones with the largest number of guns.
Skin slip occurs in dead bodies and is a natural part of the decomposition process. Over time (from the minute a person dies), their skin begins to loosen. This loosened upper layer of skin will often get large blisters that fill with oedema (edema I guess outside of European English? - basically it's bodily fluids, mostly water).
A blister is a small pocket of fluid in the upper skin layers and is one of the body's responses to injury or pressure. The feet are particularly prone to blisters. Ill-fitting shoes or friction can damage the skin, and a blister forms to cushion the area from further damage as it heals. If the blister is left unpopped, the body gradually absorbs the fluid as the underlying skin recovers. This can take around one week.
