This article talks about a recent development that a team of scientists have recently uncovered. This development is that based on genetic markers the scientists have created a test to help predict the lifespan of humans. The test shows that some people are genetically predisposed to live 5-10 years longer than some of their counterparts. The test is based on 21 different genetic locations, and how they pertain to getting certain diseases such as Alzheimer's, or Lung cancer. Predisposition to these diseases is thought to be cause of much of the variation in the lifespan predictions. Interestingly, the student didn't find any information about other types of cancers, and is thought to be related to this specific time period(present). This idea came up because in the past even if a person was predisposed to get Lung cancer, there wasn't as great of a chance as there is today, due to the smoking epidemic. In the future, scientists hope to more precisely understand these genetic markers, and eventually try to slow down the aging process.
