You probably know some parents who bubble-wrap their kids. Imagine how they would respond to the idea their 12 year-old son would spend a month sailing across the Atlantic in a leaking ship Petersburg as the interpreter for the country's first diplomatic mission to Russia.
But Abigail Adams did. When her son John Quincy asked to forego a second trip with his father to France so he could stay home and prepare for Harvard, Abigail urged him to go:. It is not in the still calm of life, or the repose of a pacific station, that great characters are formed. The habits of a vigorous mind are formed in contending with difficulties.
Great necessities call out great virtues. When a mind is raised, and animated by scenes that engage the heart, then those qualities which would otherwise lay dormant, wake into life and form the character of the hero and the statesman. Which is exactly what happened. John Quincy Adams went on to a long career in public service as a Representative, Senator, and President. While greater overall physical activity was associated with increased occurrences of spinal pain, the nature of this relationship depended on the intensity of activity.
Increased time in vigorous physical activity predicted future spinal pain, while increased time in moderate intensity activities tended to protect against spinal pain. Vos, T.

Here's what experts suggest Another reason to jump into the pool: Swimming can help improve memory, mood and immunity. A mere four seconds of all-out exercise, repeated two or three dozen times, could be all many of us need to build and maintain our fitness, strength and physical power, according to an inspiring new study of the potency of super-quick workouts.
The findings expand on other, recent studies showing that four-second interval workouts beneficially affect metabolism and muscles in adults of various ages.
But they may also highlight new concerns about what we miss if we make our workouts too brief. Almost anyone with even a passing interest in exercise and health has heard by now of high-intensity interval training, or HIIT, a topic I have covered frequently in this column.
A typical HIIT workout involves repeated, short bursts of arduous effort, known as intervals, interspersed with rest periods. For generations, athletes interval trained to amp their speed and performance.
In past studies, workouts with intense intervals ranging in length from four minutes or even less improved aspects of health and fitness to the same or a greater extent than much longer sessions of continuous, gentler exercise, like jogging or walking. For HIIT fans, the high-intensity workouts often represent their primary or only form of exercise. ETPrime stories of the day Investing Bad bet or value buy?
