Fun facts about your age
The oldest verified person ever was Jeanne Calment of France, who lived to 122 years and 164 days (1875-1997). A person born today will have their heart beat approximately 2.5 billion times in an average lifetime. Your body completely replaces most of its cells every 7-10 years, meaning the "you" of today is physically almost entirely different from the "you" of a decade ago.
