The "90+ Study" on AGING -- ( 60 MINUTES
Part1
video , Part2 video)
with a huge sample of 1,600 out of 14,000 participants
and 33 years !
Dispels some common theories:
- 45 minutes of moderate exercise per day is the sweet
spot (even 3 hours per day didn't beat 45 mins).
Two drinks per day of ANY kind of alcohol
reduces risk of death. ***- 1-3 cups of coffee per day was better than none !
- Anti-Oxidants & some Vitamins DON'T make a
difference, including E, A, C & Calcium.
- Those a little over-weight outlived the underweight !
- You can have Plaques & Tangles all over your brain
and NOT be demented !
- Low blood pressure leads to LESS life-expectancy than
high !
and maybe causing Dementia created by micro-strokes.
- Risk of developing Dementia doubles every 5 years -
starting at 65. If u don't get it before 80 u still can get it after.
Caffeine from four cups of coffee protects the heart with the help of
mitochondria. caffeine improved the functional capacity of endothelial cells,
which line the interior of blood vessels, (and the effect involved mitochondria,
the cell's energy powerhouses).
It protected heart muscle cells from
cell death, and triggered the conversion of fibroblasts into cells containing
contractile fibers—all crucial for repair of heart muscle after myocardial
infarction.

Many studies tend to place former
drinkers in the same group as lifetime abstainers, referring to
them all as “non-drinkers,” .
But former drinkers typically have given up or cut down on
alcohol because of health problems .
The new analysis found that former drinkers actually have a 22%
higher risk of death compared to abstainers.
Their presence in the “non-drinker” group biases the results, creating the
illusion that light daily drinking is healthy.
For the new study, the researchers pooled the data and then made adjustments
that took into account problems like the “former-drinker bias.”
The combined adjusted data from the studies showed that
- neither occasional drinkers
(less than 1.3 grams of alcohol, or one drink every two weeks)
- nor low-volume drinkers (up to
24 grams a day, or nearly two drinks)
had a significantly reduced risk
of death.
The researchers found a slight, but not significant, increased risk of death
among those who imbibed 25 grams to 44 grams daily, around three
drinks.
And there was a significantly increased risk of death for people who drank
45 or more grams of alcohol a day, the results showed.

Women with high physical fitness at
middle age were nearly 90 percent less likely to develop dementia decades
later, compared to women who were moderately fit, according to a study
published the March 14, 2018, online issue of Neurology, the medical journal of the American Academy of Neurology. The
study measured the women's cardiovascular fitness based on an exercise test.
When the highly fit women did develop dementia,
they developed the disease an average of 11 years later than women who
were moderately fit, or at age 90 instead of age 79.
"These findings are exciting because it's possible that
improving people's cardiovascular
fitness in middle
age could delay or even prevent them from developing dementia," said study
author Helena Hörder, Ph.D., of the University of Gothenburg in Gothenburg,
Sweden. "However, this study does not show cause and
effect between cardiovascular fitness and dementia,
it only shows an association. More research is
needed to see if improved fitness could have a positive effect on the risk of
dementia.... (Those fitter women might also be eating
better for instance.....) and also to look at when during a lifetime a
high fitness level is most important."
For the study, 191 women with an average age of
50 took a bicycle exercise
test until they were exhausted to measure their peak cardiovascular
capacity. The average peak workload was measured at 103 watts.
- A total of 40 women met the criteria for a high
fitness level, or 120 watts or higher.
- A total of 92 women were in the medium fitness
category; and
- 59 women were in the low fitness category, defined as a peak
workload of 80 watts or less, or having their exercise tests stopped because
of high blood pressure, chest pain or other cardiovascular problems.
Over the next 44 years, the women were tested for
dementia six times. During that time, 44 of the women developed dementia.
- 5 percent of the highly fit women developed dementia, compared to
- 25 percent of moderately fit women and
- 32 percent of the women with low fitness.
The highly fit women were 88 percent
less likely to develop dementia than the moderately fit women.
Among the women who had to stop the exercise test due to problems, 45
percent developed dementia decades later.
"This indicates that negative cardiovascular processes may be happening in
midlife that could increase the risk of dementia much later in life," Hörder
said.
Limitations of the study include the relatively
small number of women involved, all of whom were from Sweden, so
the results may not be applicable to other populations, Hörder said. Also,
the women's fitness level was measured only once, so any changes in fitness over time were not captured.
