There are constantly new studies suggesting different ways to slow both physical and mental aging. This month alone, the news has featured research suggesting the following:
- Aging with pets in place can increase life satisfaction overall, and research suggests that pets may be associated not only with less loneliness, stronger social support systems, and increased participation in the community, but also better cardiovascular health, lower cholesterol, and lower blood pressure.
- A study from the University of Leeds suggests that tickling may slow down aging. The study involved the use of electrodes on the participants’ ears to simulate a tickle-like tingling sensation. Two weeks of 15-minute daily tickling therapy were believed to improve the balance of the autonomic nervous system.
- People who are optimistic may live longer. For groups of both women and men, those who were optimistic long-term had a better chance of living to age 85 (and beyond). Optimism has been linked with goal-setting and healthier habits and, accordingly, fewer optimistic people are believe to die prematurely from stroke, heart disease, or cancer.
- Consistent with previous research, a new study by the University of Iowa has linked exercise to a healthy aging brain. Even a single bout of exercise was considered to improve cognitive function and working memory in older participants.
While there may be nothing to prevent aging altogether and/or to totally eliminate the risk of suffering from Alzheimer’s disease or other age-related cognitive decline (absent any major scientific breakthrough), in general, taking health and wellness more seriously from an earlier age may improve quality of life and independence down the road.

These days, life expectancy is longer than ever. We have previously blogged (for instance, here and here) about some considerations and consequences of having a longer life expectancy. A recent article in The New Yorker considers aging, and in particular, anti-aging now that people are generally living longer. The online version can be found here: Can We Live Longer but Stay Younger?
One of the problems with living longer, as highlighted in the New Yorker article, is that we still must deal with the challenges and realities of aging. What we really want is not eternal life but rather, eternal youth.
The article discusses several efforts to address or counteract the types of issues that we face as we age. For instance, a geneticist at Harvard has successfully extended the life of yeast, and is moving on to human trials. A Harvard molecular biologist, George Church, has had success reprogramming embryonic stem cells to essentially turn an old cell into a young cell. Church’s work has been done so far on mice and dogs, but there are plans to commence human clinical trials within the next five years.
The goal of the work being done by Church is to live better, not necessarily longer: “The goal is youthful wellness rather than an extended long period of age-related decline.” The article discusses the nature of this age-related decline, through the illustration of a “sudden aging” suit that allows the wearer to experience the physical challenges of aging, including boots with foam padding to produce a loss of tactile feedback, and bands around the elbows, wrists, and knees to simulate stiffness. The point of the aging suit is to help create empathy and understanding about how difficult each and every task (an example was reaching up to a top shelf and picking up a mug) can be for older adults, both physically and mentally. So the question becomes, if we are living so much longer, but with age, every day and every task becomes much more difficult, what can we do to counteract that?
The work being done related to anti-aging and the creation of products to make older people’s lives easier is interesting and seems to be moving in new directions. For instance, the article mentions the difficulty of marketing certain products aimed at older people, because we do not like the idea of buying something that reminds us that we are old. So instead of selling a personal-emergency-response system to send an alert and seek assistance in the event of a fall, or some other physical emergency, in the form of a pendant worn around the neck, it is suggested that the most effective such device would be an iPhone or Apple Watch app.
Unfortunately, the issue of dementia is still a concern. There still does not appear to be a cure in sight for Alzheimer’s or other forms of dementia. The causes remain unclear. The effects, however, are evident. One of the individuals mentioned in the article was Professor Patrick Hof, who studies brains. On the physical effects of dementia on our actual brains, Professor Hof notes that “[y]ou can’t tell any difference, even under extreme magnification, between an aging non-demented brain and a younger human one…But, holding an Alzheimer’s brain in your hand, you can see the atrophy.” It appears that there is still a lot of work to be done in this area, in particular.
