Question 45 of 433
Which clock is the best?

The short answer
For predicting who gets sick and who dies, GrimAge and DunedinPACE perform best in research. No clock is yet good enough to steer treatment for one individual.
This distinction matters. In a study of thousands of people, a clock can clearly separate the fast agers from the slow. For one person on one day, the result can wobble by a couple of years depending on the lab, the time of day, a recent infection, or plain statistical noise.
