And actually we don't spend nearly enough money looking for those things, looking for those tiny things that may or may not work, but which, if they do work, can have a success absolutely out of proportion to their expense, their efforts and the disruption they cause.

But, even in narrow cost benefit terms, it makes sense to spend more on treating depression.

One gourmet coffee, one, is more we spend more on than we are spending to feed kids for an entire week in our schools.

It will cease to exist when it spends 6.5 per cent of its gross national income on scientific research while we spend 0.2 of our income on production.

The second thing we need to do is while we're spending billions and billions of dollars all over the world building an electronic health record, we make sure we put a place history inside that medical record.
