The number of elderly is rising worldwide, and it is estimated that average life expectancy in Europe will reach 100 by the end of the century.
At the same time, old age and what we expect from it are changing. An extensive research project at the University of Gothenburg’s Sahlgrenska Academy has spent a number of years comparing the elderly of the 1970s with those of today. The project, known as the H70 study, reveals that old age has changed drastically in a number of ways.
For example, the proportion of elderly with schooling beyond secondary level has risen from 14% to almost 40% for both genders. This is reflected in a better performance in intelligence tests by today's 70-year-olds than their counterparts back in the 1970s.
The proportion of married people has increased, as has the proportion of divorcees. The elderly are also now more sexually active, and the number with sexual problems such as impotence has fallen.
The results of the long-term study can also be contradictory, not least when it comes to social networking:
“The H70 study shows that the elderly are more outgoing today than they were in the 1970s – they talk more to their neighbours, for example – yet the percentage of elderly who feel lonely has increased significantly,” says professor Ingmar Skoog from the University of Gothenburg’s Sahlgrenska Academy, who leads the study.
Old people’s mental health does not seem to have changed, however. Dementia disorders are no more prevalent today than they were 30 years ago, and while more old people consider themselves to be mildly depressed, more severe forms of depression have not become more common. Meanwhile the elderly are coping better with everyday life: the number needing help with cleaning has fallen from 25% to 12%, and only 4% need help taking a bath, down from 14% in the 1970s.
“Our conclusion is that pensioners are generally healthier and perkier today than they were 30 years ago,” says Skoog. “This may be of interest both in the debate about where to set the retirement age and in terms of the baby boomers now hitting retirement age.”THE H70 STUDY

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
