> something many people are hoping to solve in healthcare
Respectfully, the solution is don't smoke, exercise, eat well, sleep, avoid stressors... These aren't easy problems but their solution isn't at the individual patient level and is a simple question of capital and political will.
The 'hope' envisages a product to temporize the solution while extracting large payments.
Nope, I believe you are wrong: a path where we, for example, forbid smoking because the statistics point at it correlating with many health problems, is a world where we use the same statistical tool to prescribe human behavior to the last detail. It is not just about smoking, alcohol, late night dancing, switching sex partners, fast driving on a track, paragliding, skydiving, climbing, car driving, bicycle driving, motor biking, even staying late for astronomical observations (sleep patterns?)... all carry insignificant risk when looked at statistically.
> ...avoid stressors...
Most stress is caused by a conflict between our expectations/motivations and the reality (everyone else's).
