"If a reasoning human being loves and values life, they will want to live as long as possible—the desire to be immortal. Nevertheless, it’s impossible to know if they’re going to be immortal once they die. To do nothing doesn’t help the odds of attaining immortality—since it seems evident that everyone will die someday and possibly cease to exist. To try to do something scientifically constructive towards ensuring immortality beforehand is the most logical conclusion."
