The heritability of variety seeking in the food domain was estimated from a large sample (N = 5,543) of middle age to elderly monozygotic and dizygotic twins from the "Virginia 30,000" twin study. Different dietary variety scores were calculated based on a semi-quantitative food choice questionnaire that assessed consumption frequencies and quantities for a list of 99 common foods. Results indi...

BACKGROUND There is evidence of an association between poor oral health and mortality. This association is usually attributed to inflammatory and nutrition pathways. However, the role of health behaviours and socioeconomic position has not been adequately examined. The aims of this study were to examine the association between oral health and premature death among middle-aged men and to test wh...

OBJECTIVE To examine material and behavioural factors as explanations for occupational class differences in health, while taking into account the interrelations between these two groups of factors. METHODS Data from cross sectional surveys among middle aged women and men employed by the City of Helsinki (n = 6062, response rate 68%) were used. The contribution of four material and seven behav...

Two experiments tested text comprehension skills in adults varying in age from 20 to 69 years. A coherence judgment task (n = 39), in which the pragmatic connection of two sentences had to be evaluated, did not yield any age effects. Both error rates and reaction times were largely independent of age. In a word recognition paradigm (n = 60), testing the strength of different text representation...

Edited by Angela Reed. (National Marriage Guidance Council, 2s. 6d.) This is a symposium written by experienced marriage guidance counsellors and edited by Mrs. Angela Reed. It is a useful addition to their series of booklets and offers their usual practical, down-to-earth approach to what is often a sadly neglected period of the human condition. There is a helpful chapter on the physical chang...

Transient global amnesia is an alarming but benign disorder of middle age, which prevents both the formation of new memories, and the retrieval of recently formed ones, for some hours. Research over the last 10 years has shed light on the epidemiology, neuropsychology, functional anatomy and differential diagnosis of this distinctive condition, and clarified its management.

BACKGROUND Frailty in individuals can be operationalized as the accumulation of health deficits, for which several trends have been observed in Western countries. Less is known about deficit accumulation in China, the country with the world's largest number of older adults. METHODS This study analyzed data from the Beijing Longitudinal Study of Aging, to evaluate the relationship between age ...

BACKGROUND New methods of R-R interval variability based on fractal scaling and nonlinear dynamics ("chaos theory") may give new insights into heart rate dynamics. The aims of this study were to (1) systematically characterize and quantify the effects of aging from early childhood to advanced age on 24-hour heart rate dynamics in healthy subjects; (2) compare age-related changes in conventional...

The environmental law as it is known today is an amalgamation of common law and statutory principles. 1 Even before specific laws came into force, there were certain common law remedies against pollution. Common law is the body of customary law of England based upon judicial decisions and is embodied in the reports of decided cases. Common law had been administered by the common law courts of E...

Several studies have shown that conflict processing improves from childhood to adulthood and declines from adulthood to old age. However the neural mechanisms underlying this lifespan asymmetry were previously unexplored. We combined event-related potentials (ERPs) and electromyography (EMG) to examine lifespan changes in stimulus and response conflict processing using a modified Stroop task. W...
