In 2010 alone, almost 20,000 Queenslanders were diagnosed with the infection and 14 of these were aged 85 and older.Increased longevity, coupled with higher rates of divorce, mean people are living longer, healthier lives and many are becoming single and seeking new sexual partners later in life.In recent years luminescence dating, improved radiocarbon dating and cosmogenic isotope dating have provided a sound database from which ice edge positions can be calculated -- but interestingly enough, the old Swedish varve chronology (developed by Dr Geer and others) was not very far out....... The red lines show the retreating ice edge before the Younger Dryas.The yellow lines show the retreat after 12,700 cal yrs BP.C Chronostratigraphic Techniques in Paleolimnology.

Organisms capture a certain amount of carbon-14 from the atmosphere when they are alive.
By measuring the ratio of the radio isotope to non-radioactive carbon, the amount of carbon-14 decay can be worked out, thereby giving an age for the specimen in question.
