How long does a body last in a coffin?

If the coffin is sealed in a very wet, heavy clay ground, the body tends to last longer because the air is not getting to the deceased. If the ground is light, dry soil, decomposition is quicker. Generally speaking, a body takes 10 or 15 years to decompose to a skeleton.
