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).
When skin is exposed to UV rays, skin cells in the outermost layer of skin are damaged, and die. Damaged DNA cells also die so as to prevent the formation of cancerous cells(known as apoptosis). The tanned skin peels off after a few days. On the one hand, skin peels to remove dead skin cells from the body. On the other, immature skin cells take over in the epidermis to make up for the skin that has been peeled off. When new, mature skin cells take over, they produce ceramide to retain moisture.
