Hi you may want to look at what Emily Porter is doing to visually analyze health data.
Have you built multidimensional visualizations? I could see a color code approach to blood test results (blue low, green nominal, and red high), but I may also want to look for trends like am I getting healthier or is there a correlation between what I am eating and how my system is responding.
From the longevity standpoint I think this data will help to optimize our current health system, but not lead to radical life extension. It may prevent premature failures.
