Researchers have discovered the “fountain of youth” for cells - but it comes with a big cost.
Some people over 60 years old were found to have immune systems that appear to be much younger in wear-and-tear, Mayo Clinic researchers announced Thursday. The immune system is what protects us from getting sick and promotes healing. With age, the immune system’s ability to protect the body from infection and disease can wane. Young immune systems are constantly exposed to new bacteria and viruses, and previous research has shown that infant immune systems beat those of adults at fighting off the invaders.
