Question: What forces have shaped America most?

Transcript: I mean the World Wars certainly did. Our American Civil Wars certainly did. The Industrial Revolution, today’s revolution into knowledge work. All these things have shaped society. But . . . but I think America’s best days are ahead. And when you really think about our country, we have a great track record. People say to me, “Well can we afford to grow older as a society?” And the answer is, “Of course we can.” We are a country that’s very inventive. We are a county that has reinvented itself. Just give you one example – older workers. Our country is ahead of most others in terms of people saying, “I’m in a better state. I’m healthier. I’m better educated. I’m gonna work longer.” Well this is gonna have an effect on them, on employers, and on government, and on the taxpayers’ burden. So we can reinvent ourselves. We’re a country that has a great and bright future.

We are a country looking towards our best days being ahead.

The moment the heart stops is considered time of death. But does death overtake our mind immediately afterward or does it slowly creep in?
