Blood tests
There may come a day when patients can measure the age of their organs through a blood test.
  • A study measured the age of specific organs in 5,676 adults and found that 20% had advanced aging in one.
  • The study found that those with accelerated heart aging have a 250% higher risk of heart failure. 
  • The study builds on the idea of "biological age," a measure of your age based on biochemistry. 

A growing body of evidence suggests age is more than just a number.
