Can a bloodtest determine when you will die?

It may sound like a science fiction project, but the technology already exists. The simple blood test can actually tell you your biological age within a decade. What is more based on life expectancy factors it can even predict just how long you have to live.

It seems that our DNA has something called telomeres at the ends of the chromosomes. It has been established by scientists that these telomeres tend to shorten as we age. So they believe that by measuring the length of these telomeres it may be possible to not only tell what the person’s age is but also when the person will die.

This can be a bit complicated because biological age is not always the same as chronological age. Two people may be 35 years old and that is their chronological age. However one may lead and active and healthy life while the other may smoke too much, drink a lot and eat unhealthy junk food regularly.

In this case the healthier person is likely to have a much lower biological age and thus live longer. Critics say that the blood test will not be accurately able to tell the biological age of a person as different factors involved in aging a person are involved. It would make an interesting albeit morbid science project to see just how accurately the test can foretell lifespans.
