Marvelous idea but it should be extended to include genetic testing as well.  The rational, well informed public should be allowed to order up genetic personal testing at will.  The benefits would be tremendous.  

Why wonder when and how you are destined to die or if you will have early onset Alzheimer's ?   One simple test and you will know what heath issues await you.  If you don't like the resulting, get a second opinion.

Such a comforting feeling.
