The device, which has been created to encourage users to stay healthy, uses laser beams to analyse crucial cells lining blood vessels under the skin.These tiny endothelial cells are a key indicator of a person’s health, and the device’s inventors say that by monitoring them they can identify those who are ageing more quickly than normal. The analysis of the endothelium – the layer of endothelial cells in tiny blood vessels called capillaries – could also suggest whether someone has cancer or dementia.Everything that goes on in your cardiovascular system, whether you are going to have a stroke or heart attack, starts off as something going wrong in the endothelium.But once the test has been refined, they claim it should eventually be possible to tell a person how many years they have left.In tests on 220 healthy people, it was clear that some had aged more quickly or slowly than expected. Having created a bulky experimental device, the inventors are designing a smaller prototype that can be worn on the wrist.
But there will be concerns that while some will alter their lifestyle to stay in optimum condition, others may take a fatalistic approach. Also insurance and pension companies could also use the information to alter premiums and payouts. Without any doubt, such discovery could affect not only life style of people, but global economy too.
