Back to basics and cost effective solutions for our sanity

Solutions in technology and science to help us survive, feel better and stay sane are ubiquitous. The progress is fascinating to follow. Each day I explore new studies, new approaches, new ideas leading towards desired solutions.

Interestingly, we appear to go back to basics; natural, simple and cost effective solutions. For example, "exercise is a magic drug for many people with depression and anxiety disorders, and it should be more widely prescribed by mental health care providers, according to researchers who analyzed the results of numerous published studies". This was highlighted by the SMU Research recently.

In addition, cost effective and simplistic solutions are attracting our attentions. It is great to know that researchers in Penn State University developed a low-cost behavioral assessment that can clue someone in to Alzheimer's disease at its earliest stage.

I'd be interested to obtain your views and examples of basic, natural, simple, inexpensive yet efficient solutions from your experience that you can comment here.
