These are both excellent points about life expectancy, thank for for sharing this information, looks like I got to learn something today. The overall point however that Marie Curie did live a long fruitful life despite her research and could be considered an excellent role model. There is often a misconception that she died young due to her research, and often the subtext of disapproval because of it. I think it's sad that it's common to belittle someone for quoting her.
