By the proper intakes of vitamins and other nutrients and by following a few other healthful practices from youth or middle age on, you can, I believe, extend your life and years of well-being by twenty-five or even thirty-five years.

Science is the search for truth.

When an old and distinguished person speaks to you, listen to him carefully and with respect — but do not believe him. Never put your trust into anything but your own intellect. Your elder, no matter whether he has gray hair or has lost his hair, no matter whether he is a Nobel laureate — may be wrong. The world progresses, year by year, century by century, as the members of the younger generation find out what was wrong among the things that their elders said. So you must always be skeptical — always think for yourself.

I believe that you can, by taking some simple and inexpensive measures, extend your life and your years of well-being. My most important recommendation is that you take vitamins every day in optimun amounts, to supplement the vitamins you receive in your food.

There is no area of the world that should not be investigated by scientists. There will always remain some questions that have not been answered. In general, these are the questions that have not yet been posed.

I have always wanted to know as much as possible about the world.

The power to destroy the world by the use of nuclear weapons is a power that cannot be used - we cannot accept the idea of such monstrous immorality.
