As we age the tubing carrying the blood to our organs get less elastic, thus making it harder for them to accomodate to initial high pulse of the chamber conctraction. Instead of the arteries adapting by swelling up and than resettling after that pulse, the walls of those arteries remain stiff and the pulse has to propagate by pushing along the line.
This gets measured by taking a sample of the systolic pressure. (if a tube is narrow pressure rises, if it it widens it lowers)
The absurd advice contained in this ‘advice’ is a mere reflection of a correlation (as in NOT causation) between CVD problems and high blood pressure.
Obviously there are extremes which should be avoided, but the silly advice to lower systolic pressure to that of an 18 yr old only causes all organs to receive less fresh blood per heartbeat. As such it’s a great way to accelerate aging of those organs due to insufficient bloodflow.
NYT silly article
As for the mention of salt reduction to lower bloodpressure… Salt intake follows a J curve. No salt is much worse than normal salt intake, too much salt is also not a good idea. No/too little Salt is unhealty
In other words yet again an observational ‘study’ drawing the wrong conclusions
Many global warming studies may be wrong as carbon dating found to be highly unreliable for organic matter over 30,000 years old
Radiocarbon dating, which is used to calculate the age of certain organic materials, has been found to be unreliable, and sometimes wildly so – a discovery that could upset previous studies on climate change, scientists from China and Germany said in a new paper.
Their recent analysis of sediment from the largest freshwater lake in northeast China showed that its carbon clock stopped ticking as early as 30,000 years ago, or nearly half as long as was hitherto thought.
As scientists who study earth’s (relatively) modern history rely on this measurement tool to place their findings in the correct time period, the discovery that it is unreliable could put some in a quandary.
For instance, remnants of organic matter formerly held up as solid evidence of the most recent, large-scale global warming event some 40,000 years ago may actually date back far earlier to a previous ice age.
“The radiocarbon dating technique may significantly underestimate the age of sediment for samples older than 30,000 years,” said the authors of the report from the Chinese Academy of Sciences and Germany’s Leibniz Institute for Applied Geophysics.
“Thus it is necessary to pay [special] attention when using such old carbon data for palaeoclimatic or archaeological interpretations,” they added.
Their work was detailed in a paper in the latest issue of the journal Earth and Planetary Science Letters.
For those hysterical ‘oh no not nuclear energy’ fanatics:
Naturally-Occurring Radioactive Materials (NORM)(Updated May 2015)
Radioactive materials which occur naturally and where human activities increase the exposure of people to ionising radiation are known by the acronym ‘NORM’.
NORM results from activities such as burning coal, making and using fertilisers, oil and gas production.
Uranium mining exposes those involved to NORM in the uranium orebody.
Radon in homes is one occurrence of NORM which may give rise to concern and action to control it, by ventilation.
Natural Ionising Radiation
In other words, if you’re afraid of radioactive materials just move to another planet.
The ‘climate scientists’ would have us believe that 0.1 drop in Ph is really very very bad. Absurd press release here We are all going to die
Reality check, Ph of oceans varies :
Dynamic patterns and ecological impacts of declining ocean pH in a high-resolution multi-year dataset
Our data demonstrate that ocean pH exhibits strong dynamic patterns over multiple temporal scales (translation: Ph of oceans is never stable), which can be linked to variation in key physical and biological drivers with known mechanistic ties to pH. Across years, pH declined strongly inassociation with increases in atmospheric CO2. Over diurnal timescales, pH also showed strong systematic variation as a result of the interplay between uptake of CO2 via photosynthesis and release of CO2 via respiration.
Ocean pH also exhibited variability at the seasonal time scale, but these patterns were more complex, with some years showing systematic increases and some showing systematic declines. This complexity is linked to annual variability in the seasonal patterns of drivers of pH Two factors tend to increase pH seasonally: atmospheric CO2 declines during the summer as it is removed by terrestrial photosynthesis, and increased solar radiation tends to increase water temperature, which reduces CO2 solubility.
Examination of 24,519 measurements of coastal ocean pHspanning 8 years (Fig. 1) revealed several patterns. First, in contrast to the historical perspective that the ocean is well buffered, pH exhibited a pronounced 24-hour cycle, spanning 0.24 units during a typical day. This diurnal oscillation is readily explained by daily variation in photosynthesis and background respiration: water pH increases as CO2 is taken up,via photosynthesis, over the course of the day, and then declines as respiration and diffusion from the atmosphere replenish CO2 overnight. Second, pH fluctuated substantially among days and years, ranging across a unit or more within any given year and 1.5 units over the study period.
National dietary guidelines were introduced in 1977 and 1983, by the US and UK governments, respectively, with the ambition of reducing coronary heart disease (CHD) by reducing fat intake. To date, no analysis of the evidence base for these recommendations has been undertaken. The present study examines the evidence from randomized controlled trials (RCTs) available to the US and UK regulatory committees at their respective points of implementation.
A systematic review and meta-analysis were undertaken of RCTs, published prior to 1983, which examined the relationship between dietary fat, serum cholesterol and the development of CHD.
2467 males participated in six dietary trials: five secondary prevention studies and one including healthy participants. There were 370 deaths from all-cause mortality in the intervention and control groups. The risk ratio (RR) from meta-analysis was 0.996 (95% CI 0.865 to 1.147). There were 207 and 216 deaths from CHD in the intervention and control groups, respectively. The RR was 0.989 (95% CI 0.784 to 1.247).
There were no differences in all-cause mortality and non-significant differences in CHD mortality, resulting from the dietary interventions. The reductions in mean serum cholesterol levels were significantly higher in the intervention groups; this did not result in significant differences in CHD or all-cause mortality.
Government dietary fat recommendations were untested in any trial prior to being introduced.Conclusions Dietary recommendations were introduced for 220 million US and 56 million UK citizens by 1983, in the absence of supporting evidence from RCTs.

let’s put this into perspective….
so 46 per 1000 live births die from any cause Indexmundi
Current India population: Current population 1.281.407.281 persons
so… 1400 over 1.3 billion… nahhh i’ll let you calculate. But it’s really not even remotely close to natural causes. But hey do believe the narrative…
