NASA astronaut Don Pettit, 70, recently returned to Earth after a seven-month mission aboard the International Space Station. While experiencing intense nausea upon landing due to the return of gravity, Pettit reported feeling significantly younger and free from aches and pains during his time in weightlessness. He described feeling like a 30-year-old again, attributing this to the lack of gravity allowing his body to heal. Pettit, a veteran of four space missions, expressed his desire to continue his space career with hopes of future flights.
