Of Mistletoe, Frankincense and Myrrh

Mistletoe has had a certain mystique about it since ancient times, probably on account of the curious way it grows. The plant is a “hemiparasite,” meaning that it can either grow in soil, or, more commonly, it can spring from the branch of a tree. Ladies probably stood under the branch in awe, admiring the pretty flowers, giving gentlemen an opportunity to take a little liberty with the fair sex.

It is said to be the world’s most popular food. We are talking pizza! Although I’m a fan, and know all about “four-cheese pizza,” I’ve never come across “pizza quattro stagioni,” or “four-seasons pizza,” that is divided into four sections with each section representing one season of the year. Prosciutto and olives represent winter, artichokes spring, basil and tomatoes summer, and mushrooms represent autumn. Of course, there is always a base of tomato sauce and cheese.

Having recently moved to Prague, I have spent many of my weekends in the Czech countryside. Life there is slow, with a usual day involving a long walk in the forest as the main event. I am often reminded by my grandmother to keep my eyes and ears peeled (my words, not hers) for wild boars – especially young ones. Now might be a good time to look at this image of these delightful beasts.

“My moma [sic] said the chimney was blocked.” Thus reads the letter from a 10-year-old girl in Wisconsin who was told by her mother that Santa Claus would not be dropping off gifts that year. The real reason? The Great Depression, a decade-long economic downturn that followed the 1929 Wall Street crash.

Just about every day we are confronted with some report about some food that is going to extend our life or accelerate our demise. Sometimes it’s even the same food! One day we are urged to use vegetable oils instead of animal fats, and the next day may bring a study informing us that soybean oil is linked with obesity. Coffee is a villain one day, a hero the next. Ditto for eggs, red wine or dairy Worried about depression? A study tells us that individuals with the highest consumption of ultra processed foods have a significantly higher risk of depression.

Best Before but Not Bad After

From grocery stores to our medicine cabinets, dates stamped on products carry a subtle authority. These "best before" or "expiration" dates guide our consumption, influence our purchasing decisions, and, in some cases, shape the ingredients list on our favourite food products. But what do these dates really mean? Who decides them, and how are they determined?

Are Levitating Trains a Health Hazard?

For anyone who flies into Shanghai Pudong International Airport, it’s a rite-of-passage to take the Maglev -- short for magnetic levitation -- train into the city. The railway is as much a tourist attraction as it is a transportation system.

I was on board the train this summer, gleefully watching the speed climb to over 300 km/hour, when I overheard the woman beside me ask if the magnetic field emissions posed a health risk.

Deceitful AI Videos Mislead Seniors on Important Health Issues

I had never received an email in Vietnamese before. My request for an interview had been written in English, and the channel I had reached out to made English-language videos, but the reply I received was a simple question written in Vietnamese: “What can we help each other develop?”

The man in the videos was white, but of course, he was never real in the first place.

Antsy About Getting Old? How about Some Ant-Yogurt?

I do get some interesting questions. How about this one? “Why in Central Europe did we as kids put a straw on an anthill, wait for the ants to crawl over it and then suck it for its sour taste? My mother did it and lived to 93!”
