Know the Spread of money when changing money for your trip.
I am no currency trader. I am just a regular traveller who flies to numerous Asian countries for work in the past and less so nowadays. Let me give you a tip on how to save money when you travel.
If you need to change money, do go to the money changers outside of town area. They have lower operating expenses, and hence can offer you better 'rates'. When I say 'rates', I mean when you change your Singapore dollars to a foreign currency, the 'spread' or the different exchange rates the money changer gives you is smaller than if you were to change at the airport. That is the most expensive and worst place to change money, aside from the banks.
Case in point, let me show you my recent trip to China. I changed money at the last minute at the Prosegur Exchange at the T1 Departure Lounge at Changi on the very day I was to depart to Guangzhou for a business trip. Yes, the airport does offer convenience, because, if you are a busy (or disorganised) person like me (sometimes), you will say, "heck this, its only a few hundred .bucks, how much can I lose anyway ?"

Groundbreaking News. Peridontal Disease could be the cause of Alzheimer's Disease
There has been recent groundbreaking news that there is a causal link between Peridontal Disease and Alzheimer's Disease. Alzheimer's patients have peridontal disease but peridontal disease doesn't necessarily lead to Alzheimer's Disease. The message to all my readers and friends, brush when you wake up, brush after meals, floss 2 times a day. There is no time to waste. You can potentially add 10 good quality of life years to your health !
As a person who has initial stages of peridontal disease, I am very cognizant of the fact that I must regularly see my dentist to manage the condition, and this additional risk is another reason for me to see him at least 4 times a year. Below is an extract from the National Institute of Health's website :
Periodontal disease (PD) is an inflammatory oral disease that affects the supporting structures of the teeth (periodontium), including gingiva, periodontal ligament, cementum, and alveolar bone [1]. The disease results from complex interactions between the dental biofilm and host defense mechanisms. Bacteria and their components like lipopolysaccharides present in the biofilm induce an intensified host inflammatory response. This cascade of inflammatory response damages periodontal structures and leads ultimately to bone loss [1]. Being responsible for disability, speech impairment, low self-esteem, and reduced quality of life, PD has become a major public health concern that burdens the global healthcare system [2].
Alzheimer's disease (AD) is a progressive neurodegenerative disorder with a prevalence increasing exponentially with age [3,4]. It is characterized by an irreversible degeneration of neurons and neural connections beginning in the hippocampus and extending to the rest of the brain. People affected by Alzheimer's gradually lose cognitive abilities and autonomy. These symptoms consequently lead to advanced dementia and eventually to death. The cognitive decline that leads to AD has been related to two cardinal neuropathological features, beta-amyloid plaques (Aβ) and neurofibrillary tangles [5,6]. The amyloid plaques consist of deteriorating neuronal processes or neuritis, surrounding deposits of a central core protein called amyloid beta (or beta-amyloid). This protein is derived from a larger molecule called amyloid precursor protein, which is a normal component of nerve cells. The neurofibrillary tangle consists of abnormal accumulations of phosphorylated protein, called tau located within nerve cells. This protein is normally present in neurons. Abnormal chemical changes cause tau molecules to form tangles inside neurons.
There is a growing body of evidence in the literature suggesting a potential association between PDs and systemic diseases, particularly atherosclerotic vascular disease, pulmonary disease, diabetes, pregnancy-related complications, osteoporosis, and kidney disease as well as AD [2]. The periodontal medicine concept has been proposed to study the interrelationship between oral and systemic health. The presence of periodontal pathogens and their metabolic by-products may contribute to the body’s overall inflammatory burden, thus promoting the development of systemic conditions [2,7,8]. It has been suggested that periodontal pathogens could promote initiation or exacerbation of systemic diseases either by entering the bloodstream (bacteremia) or by stimulating an immuno-inflammatory response through the systemic release of toxins and local inflammatory mediators such as cytokines, prostaglandins, and serum antibodies into the bloodstream [2,7,8].
Most studies have indicated that Alzheimer's patients suffer from impaired oral health, a high incidence of PD, and an affected quality of life. These oral manifestations have been justified by the cognitive and motor deficits related to AD, compromising dental care and the maintenance of proper dental hygiene [9-18].
Authors have also suggested that PD may be a risk factor for AD. Hypotheses are mainly based on the involvement of periodontal pathogens and their virulence factors in the pathogenesis and progression of Alzheimer's, either by direct invasion of brain tissue or by indirect action of the bacterial load and pro-inflammatory mediators in systemic circulation [19-22]. Thus, following the elevation of the systemic inflammatory response, periodontal infection would contribute to cerebral and vascular pathologies by altering brain function and, as a result, worsen the neurodegenerative process characterizing AD [19-29].
The purpose of our systematic review was to evaluate how is PD related to the onset and progression of AD and to determine whether patients with PD would be at greater risk of developing AD compared to periodontally healthy subjects.

Farewell Gene Hackman - my favourite character actor in the 70s and 80s.
Gene Hackman died on 27th Feb 2025, aged 93 together with his wife and dog
During my formative years in the late 70s till the early 90s, I loved to watch American movies as the country then was the global leader in soft power. Nowadays, US has denigraded its aura to something akin to a 3rd world country, with so much negative news and has seen a massive drop in the standard of living for millions of ordinary Americans. The ills of the so called richest country on earth are plenty that something like the top 5% live in absolute luxury and the bottom 50% live paycheck to paycheck, and up to 15% are homeless.
Drug use is endemic in practically all major cities, gang warfare is rampant, and the average life expectancy of American male is 7 years shorter than the average Singaporean male.
Back to the 70s, 80s and early 90s, Hollywood churned out many blockbuster movies of the 2nd World War, the Civil Rights Movement, and the Wild West to the millions of impressionable Asians who were just coming out poverty and were fed the staple of US action, love and disaster movies.
I recall Gene Hackman, as first portrayed as General Sosarowlski, the Polish General in the epic movie "A Bridge Too Far". His acting was superb and he led the doomed Polish Brigade at Arnhem which was decimated by the Germans upon landing. There were like 20 top name stars in that era who acted in that movie such as Lawrence Olivier, Sean Connery, Elliot Gould, Robert Redford, James Caan, Liv Ullman, Dirk Brogade and Ryan O'Neal to name just a few. I have easily watched this movie a dozen times, and still find it so entertaining till this day.
The other standout movie of his, Mississippi Burning, was with his portrayal of the FBI agent Mr. Rupert Anderson (he was the partner of Mr. Ward played by Willem Defoe). The movie, one of my all time favourites, was about when the FBI investigated the killing of 3 civil rights movement activists in Jessup County Mississippi at the height of the MLK movement for more c9ivil rights for black people especially in the deep South, in the 60s.
Finally, he played the villain to great effect, when he played the Sheriff of a small town, in Clint Eastwood's hit cowboy movie "Unforgiven" about a former hired killer, who came back to seek revenge for the killing of his wife and family by the deputies of that small town. He earned his second Oscar for Best Supporting Actor for that movie.
He rose to fame I believe in the movie "French Connection" which I have yet to watch.Another one thing I need to see or do for my bucket list.
Mr. Hackman, a salute to you sir, you formed many good impressions of the US everyman in my formative years. Thank you for that.
