Carbon dating wood

Archaeologists use the exponential, radioactive decay of carbon 14 to estimate the death dates of organic material.

Question: "Is carbon dating a reliable method for determining the age of things?

Radiocarbon dating can be used on samples of bone, cloth, wood and plant fibers.

The half-life of a radioactive isotope describes the amount of time that it takes half of the isotope in a sample to decay.

This provides good information, but it only indicates how long ago that piece of wood was cut from a living tree.

Radiocarbon dating can’t tell the difference between wood that was cut and immediately used for the spear, and wood that was cut years before being re-used for that purpose.
