Hon I think you maybe misunderstood your chem class.
Carbon is carbon is carbon and doesn’t know or care if it’s in a living body.
Carbon-14 has a half life of 5700 years. This means that through random decay, the approximate rate of decay is one half of a given amount every 5700 years, this of course breaks down when you reach the single-digit quantities of atoms.
Now, this has nothing to do with the stability of an atom of regular-ass carbon-12, your common garden variety carbon, which is extremely stable and would require outside influence to decay into another isotope.
