It's been proven that fitting more activity into your day can greatly improve your health.

I never could have achieved the success that I have without setting physical activity and health goals.

The Supreme Court has never ruled that Congress can use the Commerce Clause to require individuals to engage in an activity they have chosen to avoid. Yet that is precisely what Obamacare does: It forces Americans without health insurance to purchase coverage. Such a requirement is unprecedented and unconstitutional.

The most common objection that I hear to walking as exercise is that it's too easy that only sweaty strenuous activity offers real benefits. But there is abundant evidence that regular brisk walking is associated with better health including lower blood pressure better moods and improved cholesterol ratios.

When the honour is given to that scientist personally the happiness is sweet indeed. Science is on the whole an informal activity a life of shirt sleeves and coffee served in beakers.

Happiness consists in activity. It is running steam not a stagnant pool.

To have the sense of creative activity is the great happiness and the great proof of being alive.

It is now possible to quantify people's levels of happiness pretty accurately by asking them by observation and by measuring electrical activity in the brain in degrees from terrible pain to sublime joy.

It takes great wit and interest and energy to be happy. The pursuit of happiness is a great activity. One must be open and alive. It is the greatest feat man has to accomplish.

Almost no one is foolish enough to imagine that he automatically deserves great success in any field of activity yet almost everyone believes that he automatically deserves success in marriage.
