Although it is widely believed that sex no longer matters after middle age, the opposite is true, and sex often becomes more and not less important as a person grows older. Because sex is among the last pleasure-giving biological processes to deteriorate, it is potentially an enduring source of gratification at a time when these are becoming fewer and fewer, and a link to the joys of youth.Thes...

We quantify the lasting effects of childhood health and economic circumstances on adult health, employment and socioeconomic status, using data from a birth cohort that has been followed from birth into middle age. Controlling for parental income, education and social class, children who experience poor health have significantly lower educational attainment, poorer health, and lower social stat...

In an increasingly aging society, age has become a foundational dimension of social grouping broadly targeted by advertising and governmental policies. However, perception of old age induces mainly strong negative social biases. To characterize their cognitive and perceptual foundations, we modeled the mental representations of faces associated with three age groups (young age, middle age, and ...

BACKGROUND Physical performance often declines in middle age, but it is unclear to what extent this is due to biological aging. It can be difficult to determine whether such physical changes are truly age-related, as they might alternatively be explained as the negative consequences of a sedentary lifestyle. METHODS We assessed the endurance of a physically active subgroup of the population b...

Previous studies have shown that self-reported health indicators are predictive of subsequent mortality, but that this association varies between populations and population sub-groups. For example, self-reported health is less predictive of mortality at older ages, has a stronger association with mortality for men than for women and is more predictive of mortality for those of lower than those ...

A sample of 2,409 intellectually talented adolescents (top 1%) who were assessed on the SAT by age 13 was tracked longitudinally for more than 25 years. Their creative accomplishments, with particular emphasis on literary achievement and scientific-technical innovation, were examined as a function of ability level (sum of math and verbal SAT scores) and tilt (math SAT score minus verbal SAT sco...

OBJECTIVES To analyse the variability in health status within as well as between socioeconomic groups. What is the range of individual variability in the health effects of socioeconomic status? Is the adverse effect of lower socioeconomic status uniform across the entire distribution of health status? DESIGN Nationally representative telephone survey of the US population in 1996. SETTING 60...

Previous studies have demonstrated age-related deficits in implicit learning of higher order sequences in comparisons of college-age and elderly adults (e.g., J. H. Howard & D. V. Howard, 1997). This study examined whether these age deficits begin in middle age. Results showed a reliable age-related deficit in pattern sensitivity in "older" compared with "younger" middle-aged people, and age re...

BACKGROUND Seasonal influences on suicide have been studied for many years with inconclusive and contradictory findings. METHODS Data on suicide in Ireland from 1980 to 2002 was examined to ascertain the contribution of season and demographic variables to suicide. Using Poisson regression modelling and sinusoidal analysis a small seasonal effect (7% from peak to trough) was identified but age...

Humans are not ants, but we often trudge together along the same trail, neglecting to look around for alternatives. Mass delusions involve large groups holding false or exaggerated beliefs for sustained periods. Humanity has a long, sorry list of these shadow-the-leader epidemics of collective consciousness which appear obviously wrong only in hindsight. Some last for centuries: early alchemist...
