Anne C. explains what she means by rational longevity: "Supporting longevity research is acknowledging that there is nothing special about aging that makes it any less solvable than any other complex engineering problem ... There's a big difference between believing something will happen because it makes you feel better to do so, and having a goal in mind, not knowing whether it's possible or not, but being motivated to work to see if it is possible. Life extension science falls into the latter category for me. It isn't a fantasy or a daydream or an existential palliative. It's an experiment, and a project, and something well worth exploring. Whatever we can learn about anatomy and health represents data for the scientific memepool, which can translate to the potential for better lives for everyone, now and in the future."
