Million Veteran Program Surpasses 580,000 Enrollments; Faces Cut

I can tell you exactly why younger veterans have a problem with this program. It is because we don't want our genetic material in a government database. I would also wonder how this is "helpful" to veterans. Better care, perhaps. Also looks like a nefarious way to say that your ailments are not service-related, but rather genetic.
I for one would be deeply suspicious about signing up.
