The nearly immortal and very careful species is a trope that shows up in some science fiction stories. See for example the Puppeteers in Niven’s Ringworld. Note also that there’s some empirical evidence for this on a small scale. Countries which have longer lifespans generally have more risk averse populations. There’s an argument that dueling went out of style in many cultures about the same time that the likelyhood to die from a lot of diseases went down as well. I don’t know if the data really reflects that claim though.
