From a HarvardMagazine.com online archive article:
Six factors measured by age 50 were excellent predictors of those who would be in the “happy-well” group–the top quartile of the Harvard men–at age 80: a stable marriage, a mature adaptive style, no smoking, little use of alcohol, regular exercise, and maintenance of normal weight. At age 50, 106 of the men had five or six of these factors going for them, and at 80, half of this group were among the happy-well. Only eight fell into the “sad-sick” category, the bottom quarter of life outcomes. In contrast, of 66 men who had only one to three factors at age 50, not a single one was rated happy-well at 80. In addition, men with three or fewer factors, though still in good physical health at 50, were three times as likely to be dead 30 years later as those with four or more.
The book examines the lives of a group of Harvard men who have been studied from their college years all the way to retirement and, in some cases, death. Its cornerstone is the Grant Study, a longitudinal investigation conceived in 1937 and launched at Harvard in 1939. With funding from dime-store magnate W. T. Grant, researchers signed up 268 members of the classes of 1941 through 1944, in their sophomore years, for an in-depth, lifelong study of “normal” adult development.

At the Charité University Hospital in Berlin, I’ve employed what’s called intermittent fasting, or time-restricted eating, to help patients with an array of chronic conditions. These include diabetes, high blood pressure, rheumatism and bowel diseases, as well as pain syndromes such as migraines and osteoarthritis.
Low and high levels of hemoglobin are associated with an increased risk of dementia, including AD, which may relate to differences in white matter integrity and cerebral perfusion.
A blood test to detect the brain changes of early Alzheimer’s disease has moved one step closer to reality. Researchers from Washington University School of Medicine in St. Louis report that they can measure levels of the Alzheimer’s protein amyloid beta in the blood and use such levels to predict whether the protein has accumulated in the brain. The findings represent a key step toward a blood test to diagnose people on track to develop the devastating disease before symptoms arise.
This study, combined with the results of previous studies, supports the hypothesis that engaging in morning exercise may result in more weight loss compared to engaging in a similar amount of exercise later in the day. Furthermore, we observed individuals who performed most of their exercise sessions in the afternoon or evening tended to have slightly higher levels of EI and reduced NEPA and NEEx, suggesting that there are potentially important differences in the components of energy balance based on time of day exercise is performed.
“We found staggering inconsistencies between how costs of dementia are calculated across studies and our analysis strongly supports that current estimates fail to recognise the true costs of the diseases, such as Alzheimer’s, that cause dementia. Some studies have estimated that out of pocket expenses for people with dementia are up to one third of their household wealth in the final five years of their life, and that caregivers have healthcare costs that are twice as high as non-caregivers. We also found evidence that costs begin rising up to 10 years prior to diagnosis — we need to better measure and factor all these into future societal cost estimates.”
“A healthy diet and lifestyle are generally recognized as good for health, but this study is the first large randomized controlled trial to look at whether lifestyle changes actually influence Alzheimer’s disease-related brain changes,” said Susan Landau, a research neuroscientist at Berkeley’s Helen Wills Neuroscience Institute, and principal investigator of the add-on study.
PBHWB of 40–42.5 °C was associated with both improved self-rated sleep quality and SE, and when scheduled 1–2 h before bedtime for little as 10 min significant shortening of SOL. These findings are consistent with the mechanism of PBHWB effects being the extent of core body temperature decline achieved by increased blood perfusion to the palms and soles that augments the distal-to-proximal skin temperature gradient to enhance body heat
