This new method developed by the researchers can help assess the age of patients' immune systems thus predicting mortality in older adults. According to researchers from the Israel Institute of Technology (Technion) the immune age is a kind of biological clock that will help identify an early weakening of the immune system. The new model will help devise preventive measures to reduce disease and mortality Xinhua news agency reported. In the study Technion scientists along with a team from the Stanford University in California were able to quantify the changes in the immune system that happen over the years. In
