This is an area with so much noise that doing nothing can be immediately preferable to doing anything because that 'anything' might be suboptimal.

But something must be done - especially in a cognitively strenuous field. Exercise, nutrition, and 8 hours of sleep are the only consistent 'free-lunch' brain supplements a person can take outside of medication for disabilities and maybe the occasional sideways oriented substance depending on the person.

Most people want to be hot and feel good. A minority of people know how to make that happen safely. I think this is where software can really shine - by telling people exactly what to do, how often, and adjusting based on results. This site touches on the wide context of health in an 'easy to understand' yet shallow way. It leaves a lot to be desired (for example strength training) and will leave people better off but still deep in that sea of noise. Have any HNers had success with any apps or programs that they would recommend?
