The complex mechanisms of life and the very inner biological processes that regulate the expression of strings into biological functions or dysfunctions will be fully understood thanks to increasingly accurate computational models of the human's anatomy and physiology.
This will allow detecting and preventing diseases at genetic level, or treating them before they evolve into actual sicknesses. Such virtual models will also enable in-silico test of drugs before the actual treatment, thus reaching 100% accuracy and no side-effects.
Thanks to the more accurate models, diagnosis and treatment, including nutritional and lifestyle advices, will be tailored to the specific needs of individuals rather than generic symptomatic profiles.
Further advances in gene-based therapies, including genomics, proteomics, bio-photonics, theranostics, and prosthetics are envisaged, though ethical concerns may arise.
Alzheimer, Parkinson, and other degenerative diseases will be defeated. But new social diseases may emerge, partially caused by new forms of pollution (super-exposure to electromagnetic sources, contamination with technology, etc.) which can have a reverse impact on life expectancy.
Neuroscience will have to address new prevention and treatment methods for such diseases caused by use of technologies.
