Like a trip to Alpha Centauri, 4 odd light years away, the ship only gets to 0.5c max. So it takes 6 months at one g to do that so you cover maybe 1/4 ly during acceleration run, same on decel, so you are doing 3.5 ly which takes 7 years so 8 years to get there, stay say 5 years, come back so you get back to Earth 21 years later of course full of new discoveries about AC and its planets. The 7 years at 0.5c would only get you about a 15% reduction in time, so you would save maybe 2 years so ship time would be about 19 years but 21 years goes by on Earth. Not a huge jump for the crew, if you left at age 20, you would be 39 coming back and your twin would be 41.

So would you volunteer for such a trip? Since this would not be happening for at least 50 years in the future, it would be a good bet they would survive, since space craft design would be very safe by then, so would you go?
