Wat is Jonathans geheim? De oudste landschildpad ter wereld heeft de energiehuishouding van een 194 jaar oude puber

Jonathan, the world's oldest living land tortoise, is currently estimated to be 194 years old. Researchers have been investigating the biological and genetic factors that contribute to his exceptional longevity, which has allowed him to survive for nearly two centuries.

His long life has spanned significant historical periods, including a meeting with Queen Elizabeth II when she was still a princess. At the time of that encounter, Jonathan was already 115 years old.
