Any time ^_^. The first step is to come out and say that longevity research is a scientific project, not a mystical one (there's no Truth of This Universe saying we can only live 80-something years no matter the scientific might we throw at the problem). That also carries some acknowledgements we need to make: biological immortality being discovered in 2060 will do you no good if you died of a heart attack in 2030, so eat healthy, exercise, and de-stress if you're really so devoted to long life!
