According to this research from Stanford University, you can find out how old you will be when you die today

We all know our calendar age, or "chronological age." But scientists believe that what truly matters is our "biological age," which reflects the age of our cells and organs. While factors like poor nutrition, inactivity, and lack of sleep accelerate our biological age, a healthy lifestyle can keep us biologically young, even as the calendar advances.
A blood test that measures the age of your organsResearchers at Stanford University have developed a new method for measuring this biological age. The blood test analyzes thousands of proteins in the blood using a technique called "plasma proteomics." By identifying which proteins are specific to each organ, the scientists created a model that can calculate the biological age of 11 vital organs, including the brain, heart, kidneys, and lungs, separately.
A study of nearly 45,000 people found that certain organs of some people age much faster than their chronological age.
What do the findings mean?The results of the study could revolutionize preventive medicine:
Predicting mortality risk: Accelerated aging of certain organs has been shown to significantly increase the risk of death. For example, having a biologically "old" heart increases the risk of heart failure, and having an "old" brain increases the risk of Alzheimer's.
The secret to longevity: Research has shown that having a biologically young brain and immune system are among the most important factors for a longer lifespan.
Early diagnosis: Knowing which organs age more rapidly can make it possible to take precautions against diseases related to that organ and develop personalized treatment methods.
How can you slow down your biological clock?So, is it possible to prevent our biological age from advancing faster than our chronological age? According to experts, the answer is yes, and the key lies in our lifestyle.
Nutrition: Adopt a varied and balanced diet rich in vitamins, fiber, antioxidants, and omega-3s. Avoid saturated fats, refined sugars, and processed foods.
Physical Activity: Regular movement throughout life is crucial for maintaining healthy muscles, joints, and brain. Instead of running a marathon, activities like brisk walking or gardening are also highly beneficial.
Sleep: Quality sleep is indispensable not only for the regeneration of the brain but also for the proper functioning of all organs.
