A recent study by researchers from the Karolinska Institute in Sweden revealed some test readings in people who live to be 100 years old. The study included data on 44,000 Swedes who underwent health assessments between the ages of 64-99 years, and then these participants were followed through Swedish registry data for up to 35 years.
Those who have reached the age of 100 tend to have lower levels of glucose, creatinine, and uric acid from the age of their sixties onwards.
