A new test has been developed and about to be marketed which would hope to give a rough estimate of the time left remaining in your life through a simepl blood test.
It works by testing telomeres, which sit on the end of chromosones and wear away with time. The theoery goes that the longer the telomeres the longer you have to live. If the telomeres have worn away then the cell is damaged and will die off.
Now, this is going to be just one factor, given that an unhealthy lifestyle, a massive drinking habit or smoking 100 a day, is more likely to kill you before your cells die out. But this could give an outside limit to how long you will live even if you are trying your best.

Regardless of the science behind this, and whether it is valid or not, would you be interested in taking a test like this and finding out how long you have left to live?
