It is based on the fact that radiocarbon 14 C is constantly being created in the atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting 14 C combines with atmospheric oxygen to form radioactive carbon dioxide , which is incorporated into plants by photosynthesis ; animals then acquire 14 C by eating the plants. When the animal or plant dies, it stops exchanging carbon with its environment, and from that point onwards the amount of 14 C it contains begins to decrease as the 14 C undergoes radioactive decay.

Radiocarbon dating usually referred to simply as carbon-14 dating is a radiometric dating method. It uses the naturally occurring radioisotope carbon-14 14C to estimate the age of carbon-bearing materials up to about 58,000 to 62,000 years old.

    Low sex drive in women has many potential causes, including underlying medical issues, emotional or psychological problems, or work- and family-related stress. The good news is that identifying the root cause of low libido can lead to effective treatment options. It is not unusual for couples to have a disparity in their sex drives. More often than not, in a heterosexual relationship, it's the woman who has the lower libido , according to research published by the Journal of the American Medical Association JAMA. This can be distressing for both partners and even put the relationship at risk if it can't be resolved. The medical term for low libido and lack of interest in sex is hypoactive sexual desire disorder HSDD , though there is some debate as to whether or not a woman's lack of sex drive should be viewed as a disorder. Research has found that the female libido differs from that of men and that women naturally have a lower libido and think about sex less often than men.
