Having a positive outlook as we age may not only be related to mood; it may also be reflected in our physical well-being. A large longitudinal study of 3,199 men and women aged 60 and older in Great Britain has revealed a relationship between happiness and better physical function.
The time you invest in stress management may pay off in faster training results. A growing body of research shows that stress levels predict healing speed—people who experience more stress recover more slowly from illness or injury than those with less stress. Stress may come from life circumstances, such as a death or disaster, or may stem from an individual’s perception of stress, such as feeling overwhelmed by work or family matters.
It seems that debit card purchases promote the same type of frivolity in children as in adults, but when cards are swiped to pay for school lunches, the impact goes deeper than just free spending.

The health and fitness world confronts a complex paradox. Exercise causes consternation and elation, angst and joy. It can prevent—and lead to—illness and injury. Workouts can keep you out of a hospital and put you into one.
Sitting for extended periods of time throughout the day has been linked with increased risk of health problems and even with death. A new study from BMC Public Health (2013: 13 ) says that quality of life may also suffer in people who sit for long periods.

In last month’s issue of IDEA Fitness Journal, we reported that a significant number of older women spend much of the day in sedentary behavior. A new study looks at the relationship between sedentary living and mortality risk in a similar population
The potentially negative impact of extreme endurance events has recently been garnering attention. A new study takes a deeper look at the health profiles of event participants.
