Sergei Krikalev's space career left him about 0.02 seconds younger.
HERE’S THE INTERESTING PART
Sergei Krikalev's space career left him about 0.02 seconds younger. Across roughly 803 days in orbit, his high speed made time pass slightly more slowly for him than for people on Earth. Weaker gravity pushed in the opposite direction, but the speed effect won. The difference is tiny, yet it is a physical clock difference predicted by relativity—not merely a metaphor about staying young.
