Put another way, the space ship sees the image change from a red-shift (slower aging of the image) to a blue-shift (faster aging of the image) at the midpoint of its trip (at the turnaround, 3 years after departure); the Earth sees the image of the ship change from red-shift to blue shift after 9 years (almost at the end of the period that the ...
Astronauts age more slowly than people on Earth. The difference isn't noticeable though — after spending six months on the ISS, astronauts age about 0.005 seconds less than the rest of us.
It's a different kind of space age. Why astronauts age slower in space: Here’s how much younger stranded explorers will be when they return to Earth Skip to main content
Because fusion yields about 0.3–0.9% of the mass of the nuclear fuel as released energy, it is energetically more favorable than fission, which releases <0.1% of the fuel's mass-energy. The maximum exhaust velocities potentially energetically available are correspondingly higher than for fission, typically 4–10% of the speed of light.
Astronauts may not be able to quickly return to Earth or receive medical supplies, equipment, or personnel if a medical emergency occurs. The astronauts may have to rely for long periods on limited resources and medical advice from the ground. The possibility of blindness and of bone loss have been associated with human space flight.

The UET and Hidden Worlds spaceships of F.M. Busby's Rissa Kerguelen saga utilize a constant acceleration drive that can accelerate at 1 g or even a little more. Ships in the Expanse series by James S. A. Corey make use of constant acceleration drives, which also provide artificial gravity for the occupants.
More on aging well and living longer: The key to a long life is avoiding the 'poisonous 5 P's,' says one of the world's top anti-aging experts You might be overdoing it on protein and not getting ...
The Mir sample involved 13 astronauts and cosmonauts and 58 American and Russian mission control personnel. The corresponding numbers in the ISS study were 17 space travelers and 128 people on Earth. Subjects completed a weekly questionnaire that included items from a number of valid and reliable measures that assessed mood and group dynamics.
