Aging
You may not think of men over 60 when you think of sex, but it happens. A lot. And when it can't happen the usual way, they are willing to pay for it - and they pay more and use less protection if they are a regular client.
Obviously the assumption, or documented medical fact, is that both parties are disease-free, but it still involves a certain amount of trust - and a certain amount more money.
The new survey in the American Journal of Men's Health asked about the habits of American men between the ages of 60 and 84 who pay for sex and found that the older they were, the more frequently…
A paper in the International Journal of Epidemiology seeks to dismiss the concept of 'fat but fit' and instead suggest that the protective effects of high fitness against early death are reduced in obese people.
The detrimental effects of low aerobic fitness in older people have been well documented but few studies have investigated a direct link between aerobic fitness and health in younger populations. A study in Sweden followed 1,317,713 men for a median average of 29 years to examine the association between aerobic fitness and death later in life, as well as how obesity affected…
It's not enough to stay fit as you age if you want to avoid falls, according to an analysis of how many hours older people exercised and how well they performed on four balance tests.
Every year around 30 percent of all people aged 65 and older experience a fall. In the same age group, falls account for 40 percent of all injury-related deaths worldwide. Injuries from falls can have serious consequences. One in four seniors who break their hip die within a year, and quality of life can be greatly reduced for survivors.
Even if older people are active, they need to work specifically on their…
A commonly used skin care ingredient is one of several newly identified compounds that can mimic the life-extending effect of a starvation diet, finds a new lab study.
Calorie restriction, a dramatic reduction in calorie intake, has been found to slow down the aging process in several animal models. Mice weaned on it from birth live longer but to-date it has not been shown to work in humans, since such an experiment on babies would be a human rights violation. Efforts are on to try and create drugs that can reproduce this effect, without the side effects of starvation.
Toward the goal of…
The flu virus infects up to one-fifth of the U.S. population each year and kills thousands of people, many of them elderly. A new study explains why the flu vaccine is less effective at protecting older individuals, the people it is supposed to protect.
Flu vaccines, which contain proteins found in circulating viral strains, offer protection by eliciting the production of antibodies -- proteins that help the immune system identify pathogens and protect against infectious disease. While vaccination is considered the most effective method for preventing influenza, it is less effective in…
Many strokes that required immediate treatment in emergency rooms may have been preventable, but stroke prevention has not advanced the way therapy for acute stroke has. Stroke prevention has fallen by the wayside as stroke patient outcomes have improved but the close monitoring of blood pressure, cholesterol levels and cardiac conditions remain important, finds a paper in JAMA Neurology.
Using a prevention scale they developed for this study, University of California Irvine neurologist Dr. Mark Fisher and colleagues discovered that 76 percent of acute stroke patients exhibited some degree of…
Two studies conducted 20 years apart in England reveal an apparent increase in healthy ageing, or years lived healthily, reflecting less cognitive impairment; and an increase in the proportion of life lived healthily, through a larger proportion of years lived with disability but less rather than more severe disability. The research from Professor Carol Jagger at the Institute of Health and Society, Newcastle University, UK, and colleagues is published in The Lancet.
Whether rises in life expectancy result in increases in good quality years of life is of profound importance worldwide, with…
Women are now spending fewer years with cognitive impairment but more years with disability compared to 20 years ago. We're living longer but senior years are still marked by declines in physical well-being even as mental acumen remains better than in decades past. In most developed countries worldwide life expectancy is increasing at the rate of at least two years every decade, and, for life expectancy at age 60, shows no sign of slowing down.
Scholars writing in The Lancet have shown that between 1991 and 2011 women's life expectancy at age 65 increased by 3.6 years but they…
Living longer usually means a longer dotage, with more pills and disease risk for more decades rather than aging well. What would be better? Extended young adulthood, when we are at our primes.
In the study in eLife, researchers administered an antidepressant called mianserin to Caenorhabditis elegans, a type of roundworm used frequently in research. In 2007, they discovered that the drug increases the lifespan of roundworms by 30-40 percent and they wanted to find out how so they treated thousands of worms with either water or mianserin and looked at the activity of genes as the worms aged.…
Dietary restriction enhances the expression of the circadian clock genes in peripheral tissue, according to research in Cell Metabolism which found that dietary restriction, induced by reducing protein in the diet, increased the amplitude of circadian clocks and enhanced the cycles of fat breakdown and fat synthesis.
This improvement in fat metabolism may be a key mechanism in explaining why dietary restriction extends lifespan in several species, including the flies in this study.
And it envisions a future where humans can take a drug that would allow them to reap the potential health…
