New Scientist Breaking News - Cosmic rays may prevent long-haul space travel
Maybe I'll get to be an astronaut after all. Barring major genetic modification or technical breakthroughs, space travel may be too hazardous for the young. Those past reproductive ages, perhaps only 30 years from death, might be risking only 5-10 years at the end of their life. Unfortunately dementia seems to be fairly likely, based on mouse experiments.
Space diets may yet go high fiber.
