Do human bones last forever?

Bones do decay, just at a slower rate than other types of organic material and tissue. Based on a wide range of extrinsic and intrinsic factors, bone can last for a few months to a few geologic eras, but the truth is that nothing lasts forever.

Do bones decompose in a coffin?

By 50 years in, your tissues will have liquefied and disappeared, leaving behind mummified skin and tendons. Eventually these too will disintegrate, and after 80 years in that coffin, your bones will crack as the soft collagen inside them deteriorates, leaving nothing but the brittle mineral frame behind.

Bones - Dead

Do skeletons decompose?

In neutral-pH soil or sand, the skeleton can persist for hundreds of years before it finally disintegrates. Alternately, especially in very fine, dry, salty, anoxic, or mildly alkaline soils, bones may undergo fossilization, converting into minerals that may persist indefinitely.

Do bones feel pain?

Bone pain usually feels deeper, sharper, and more intense than muscle pain. Muscle pain also feels more generalized throughout the body and tends to ease within a day or two, while bone pain is more focused and lasts longer.
