We recognize that violence is a learned behavior. One of the best classrooms for learning violence is in the home.

What has too often happened in the past is that people have threatened punishment but have failed to carry it out. It's imperative in any initiative that is undertaken that punishment be real and that there be truth in sentencing, and that the truly dangerous offenders - the recidivists and the career criminals - be put away and kept away.

My earnest hope is that what we started in terms of building partnerships with communities across America will continue, that we will continue our efforts to reduce crime and violence.

We're building on an international network with many others for the passage of the Americans with Disabilities Act. There are so many things we can do to carry forward policies.

We separate problems with the brain into neurological and psychiatric, and it's because it's stigmatised still. Mental illness is still stigmatised. Imagine if we treated people with cancer like that. Just because your personality changes and your behaviour changes, all of a sudden you are put in a different category.

What public health really is is a trust. That's why I used the term 'Betrayal of Trust' as the title of my book. It's a trust between the government and the people.

If our society continues to support basic research on how living organisms function, it is likely that my great grandchildren will be spared the agony of losing family members to most types of cancer.

I am a very simple guy. Of course, popularity matters a lot, but for me, my health and family come first.
