Is coffee the mother of alertness?

As the drinking of coffee is now a topical subject, I was intrigued to read that the US military is coming to the rescue of fatigued civilians with an algorithm that tells you exactly how much coffee to drink to maintain peak performance.

The caffeine optimisation tool has been designed to maximise alertness while avoiding excessive caffeine consumption.

Tests have suggested that the system, call 2B-Alert, easily outperforms the US army’s guidelines on caffeine use. It helped subjects to cut their caffeine intake by as much as two thirds without diminishing the alertness. The tool, available to use online, allows a user to specify their desirable peak alertness periods, then sleeping schedule, the minimum level of alertness they want to maintain and the maximum daily caffeine intake.

Jacques Reifman, a senior research scientist for the US army, said: “If you pull an all-nighter, need to be at peak alertness between say, 9am and 5pm, and desire to consume as little caffeine as possible – when and how much caffeine should you consume? This is the type of question 2B-Alert was designed to answer.”

For decades the US military has plied servicemen with amphetamines, steroids and painkillers in the name of improving performance. More recently it has turned to stimulants such as Ritalin and Adderall in the hope of bolstering cognitive stamina and memory. But few substances have proved as useful in combating exhaustion and boredom as caffeine. The US army prizes its ability to improve risk-related judgement and impulsiveness during prolonged sleep deprivation. The ready meals provided to troops in battle have contained caffeine-fortified snacks such as beef jerky and apple sauce. The algorithm offers advice on when they should be consumed. For instance, an average person who gets six hours’ sleep, wakes at 7am and wants to be alert between 10.30am and 6.30pm is advised to consumed 200mg of caffeine – equal to about a large mug of filter coffee – at 10am and again at noon.

Tests suggest that the caffeine solutions proposed by the algorithm either required on average 40 percent less caffeine or enhanced alertness by 40 percent, compared with how US troops had used coffee. The research was published in the journal sleep. The High-Performance Computing Software Applications Institute of the US army has been working on the algorithm for several years. Its researcher had suggested that the algorithm could be embedded in a smartphone app that could be used by people who must deal with irregular hours. The institute has also created a “psycho-motor vigilant risk test” that measures the speed at which people respond to a visual stimulus and gauges how alert they are.

The researchers have suggested that this could be part of the app that also utilises sleep data from fitness tracking devices to general bespoke sleep and caffeine schedules.

This study is perhaps the most useful I’ve so far read which explains the very nature of the use of caffeine for alertness.

 

Gold has a clear message

I always reckoned that when the price of gold rises dramatically, it points to instability in world markets for the simple reason that political mayhem plays a negative role throughout. Last week Gold rose above $1400 an ounce, its best level for almost six years, as a weaker dollar, economic concerns and geopolitical tension sparked a flight to safety. Demand for gold has jumped since the Federal Reserve indicated last Wednesday that it was likely to cut interest rates for the first time in a decade soon.

Oil prices rose 1pc to just over $65 a barrel despite US President Donald Trump saying he aborted a military strike on Iran on Thursday. However, the tension as for the possibility of a future conflict with Iran remains a worrying aspect – on Wall Street, both the S&P 500 and DOW JONES INDUSTRIAL average made further gains. In London, the FTSE 100 ended almost 17 points, or 0.2pc, at 7,407 points.

Investors’ attention now turns to next weeks’ planned meeting between Mr Trump and Chinese Leader Xi Jinping in Japan with hopes of a deal to end a trade war between the US and China that has hit global growth. Unless this is resolved soon, the effect to both parties will be catastrophic.

Trump’s insistence of having the upper hand in his quest to subdue nations will eventually become counterproductive.

 

DON’T GET YOUR KNICKERS IN A TWIST…

We are now told that sleeping less, later in life, could be an early warning sign for Alzheimer’s, experts reveal. Yet earlier on this year we were warned that excess of sleep has the same effect on the brain and could also trigger heart attacks. The latest findings conclude that British citizens in their 50s, 60s and 70s may be at greater risk of dementia if they are getting less shuteye than they did in the previous decade.

In a study, they were found to have higher levels of a protein that clumps in the brain and is thought to cause the disease. However, much lower levels were found in those who managed more or the same amount of sleep as they got older. It is well known that a lack of sleep may lead to dementia, but the new findings suggest this process starts in middle age.

The results come from brain scans of 101 participants by researchers at University of California, Berkeley. They said prioritising a good night’s sleep, every night, was vital, along with maintaining regular sleep times, cutting out caffeine and alcohol near bedtime and minimising distractions.

Tau, a harmful protein linked to dementia was also found in higher levels in those who got less sleep in their sixties. The study published by the journal JNeurosci suggests that sleep monitoring could detect the early signs of dementia before any symptoms start.

I’m truly baffled and confused by studies that reflect the opposite from previous ones, to the extent that worrying about dementia will probably trigger it off.

To conclude, all I can say: The Lord be praised and leave the rest to destiny. You will no doubt be rejuvenated.

A BUNGLING NIGHT TO FORGET

On Tuesday night I watched the BBC’s programme where the remaining five candidates for the leadership of the Conservative Party and, eventually, the next prime minister, were questioned by the public. I found myself utterly disappointed with the way the whole evening was so badly organized and how it turned out to become a mish-mash, due mainly to the host, Emily Maitlis, who struggled to control the debate.

As for the contestants none, even Boris Johnson, failed to shine. He was caught on many of his policies during this fractious and inconclusive debate on live TV. His insistence that, come what may, we must leave the EU on October 31, or the public will look on ‘us with mystification’ is quite frankly, a load of tripe. No one there, and many watching, believed him since they know that his ambition to become prime minister will force him to change and compromise.

As for Jeremy Hunt, he was nervous to say the least, but his worst moment was invoking his children in an attempt to divert from a direct question about Trump’s recent tweets. As for Michael Gove, despite his articulation, there was a sense that he also cannot be trusted. He is much too pompous to get people to back him. His confidence that he is the best man to be prime minster struck me as overdoing it, to the point of irritation.

Sajid Javid’s worst moment was trying to explain how money would solve the problems caused by Brexit at the Irish border. Theresa May, who tried to solve this problem for over two years and was willing to spend money to achieve it, did not succeed, despite her perseverance. I doubt whether he would be able to miraculously succeed where many others have failed.
Last but not least, I developed a great regard for Rory Stewart (alas, now eliminated) who won the sympathy of many people for his honesty and appearing to back the underdog, even when the system would not have allowed him to succeed. In a different world he might have had a chance in his wish to overturn the common assumption that the Establishment is not driven to be more disposed to the plight of others when money is their prime factor.

All in all, the programme was a fiasco of huge proportion, but also rather boring in every possible aspect. Perhaps politicians of our present generation lack the greatness of those who made Britain a force to be reckoned with during the last century. I fervently hope this is only a phase which will not last. We deserve a lot better.

SEX GALORE, NO MATTER WHAT…

We seem to be going through a period where politically we are in shambles and the weather is following suit, in the middle of June. In addition, even sex infection cases are at a 40-year high, as over-65 singles find new lovers bursting on the scene without perhaps taking the required precautions.

Figures show sexually transmitted infections such as gonorrhoea are rising as casual sex is having an unprecedented free time. Doctors have blamed the surge on dating apps such as Tinder, Older Britain’s Finding New Sexual Partners After Divorce, or Bereavement; and TV shows such as Love Island, normalising irresponsible casual sex.

More than 56,000 people were diagnosed with gonorrhoea last year – up by more than a quarter since 2017. Pensioners experienced the highest proportional increase, with cases surging by 42% last year to 336. Cases of the sexually infected infections (STI) have been rising in both men and women for years – but have now reached their highest level since 1978.

Experts said online dating means that older people are finding new sexual partners after becoming widowed or divorced – but warned that many do not use condoms due to low pregnancy risk. Dr Mark Lawton, from the British Association for Sexual Health and HIV, said: ‘Previously as older people are widowed or divorced, that would spell the end of their sex lives. But now, quite rightly, they want to get back there and have sex again. The problem is they’ve not used condoms for 35 years in their marriage so they don’t start using them now.’ He added: ‘Many of these people would make sure their grandchildren have condoms, but don’t use them themselves.’

The data from Public Health England revealed an overall 5% annual increase in STIs to 447,694 cases. Almost half of these diagnoses were for Chlamydia with 15-24 year olds the most commonly affected. However, rates of the STIs also increased by more than a quarter among the over-65s. Dr Lawton said: ‘Attitudes to sex are changing thanks to shows like Love Island which makes people feel that having causal sex with lots of different people is normal and they should be doing it.’ He added that dating apps had made casual sex easier: ‘You can just swipe right – you don’t have to take them out to dinner anymore.’

The data also revealed there were 7,541 cases of syphilis which has often been regarded as a Victorian disease. The figures show that rates have more than doubled in a decade. Dr Gwenda Hughes, from Public Health England, said: ‘STIs can pose serious consequences for health – both your own and that of current and future sexual partners. No matter what age you are or what type of relationship you are in, it’s important to look after your sexual health.’

I believe the internet is to blame. Both young and old seem to be transfixed to what they see or hear. The sooner they realise that they have been conned, the better.

SHOOTING THE CORPORATION IN THE FOOT

When the BBC announced that elderly people will be subject to paying a TV licence of 154 sterling pounds beginning from next year, I could not believe the hypocrisy of an institution that spends millions of pounds for its own glory and for the glory of some of its famous employees; whilst willing to penalise people beyond the age of 75, irrespective of their ability to survive the current financial instability that the nation is now facing. I for one, in line with thousands of other people, would rather face jail than succumb to this blackmail and even perhaps throw our television out of the window and live miserably thereafter.

I saw the hypocrisy of the BBC management trying to justify this horrible move on television and thought what a load of brigands they looked, and the cheek of their decision to deliberately penalise the older generation simply for living too long and thus becoming a burden on their institution.

Two days later, 230,000 people were disgusted enough to sign, in one day, a petition, accusing the BBC of double dealing and trying to send the elderly to prison for failing to pay the licence, irrespective of their age beyond 75. The headlines in most newspapers condemned the BBC and accused the corporation of an appalling betrayal, suggesting they should cut their own salaries to start with, and stop squandering money as if they were responsible for printing it.

This latest scandal is that cash from over-75’s forced to buy TV licences will help to top generous BBC staff pensions. Some former corporation bosses are entitled to six-figure hand-outs in retirement as members of a gold-plated payment scheme. The BBC, nevertheless, faces a financial crisis with a black hole in its pension pot, its accountant revealed. It plans to spend two billion pounds to plug the gap by 2028 at a rate of around 200 million pounds a year, some of which will come from licence payments.

Stripping 3.7 million households of the TV licence from June next year will fuel ever more violent backlashes against the BBC to strip. They will live to regret it. All their present supporters will line up against them and I can never see the corporation being able to quell the outcry that will follow.

Shame on you BBC for you have proved unworthy of the task you have been given! The present management lot should now do the honourable thing and resign.

Boris The Gambler

I have no doubt that Boris Johnson will win the present contest to become the next prime minister of this country. However, given his present policies regarding Brexit, his fate with the EU will be similar to his predecessor, Theresa May who unwittingly thought that by her perseverance she would manage to win on the day and cow Parliament into accepting her deal.

However, in line with European negotiators, I do not believe that with his present stance Johnson is unlikely to be able to keep his promise to deliver Brexit by 31 October. This was confirmed by senior EU sources. Political planning in Brussels is now based on the assumption that Britain will not leave the EU on the present deadline, itself an extension from the original date of 29 May.

Even the boldest prime minister for a No Deal will have to demonstrate he has had one serious try to reach a deal and that means an extension, according to a senior EU official. ‘ Johnson will want to last more than few days in power so he will need to try getting it over the line. He, or whoever it is, will not be capable to hide the need for an extension.’

Because of the tight timetable it is unlikely that formal negotiations will open until October, only allowing a few weeks to conclude a deal that has, so far, eluded negotiators for over two years. Despite the magical ability of Boris Johnson, I believe such a goal will elude his ambition to govern as prime minister which he has hankered to achieve over the years.

I would rather wait to see the outcome – If I’m right, his tenure will then be short lived.
