Each of us may go through moments of uncertainty at work, and recognising these signs could be crucial in preparing for change.

We have explored gestures, behaviours and situations that could indicate a threat to your job position, with the aim of providing awareness and inspiration to react positively in such circumstances.

Some of these situations taken individually may not be indicative of such a drastic consequence as dismissal, but taking a moment to carefully observe each situation and reflect on your personal experience is nevertheless a way to prevent unpleasant situations from occurring.

In some of these cases, however, one is not appreciated and one is not to blame for this: if it happens, it is good to look around for a new opportunity.

It may sound like a trivial question, but in fact it is not trivial at all; on the contrary, it holds within it very important physical and philosophical questions. The Washington Post noted that this question is stirring up some of the people on Twitter these days.

The debate was generated by a tweet from journalist Jacqui Deevoy, who wondered how it was possible that the sun had 'changed colour' from what she remembered as a child. The answer, however, is one that leaves one somewhat appalled, as there is no real unequivocal answer.

After all, children do not make a mistake by drawing the sun as a big yellow ball, but it is not a completely right answer. After all, light is just the perception of the wavelength of radiation emitted by the sun, and therein lies the whole secret.

A large part of human activities that can have an impact on the environment is carried out at sea (fishing, maritime transport, coastal tourism), in the oceans and on their shores. This obviously has a very negative impact on the environment if citizens and companies are not educated to be more respectful of the waters.

The 'Blue Economy' is a key project for the European 'Green Deal', obviously a series of measures to make energy production and the lifestyle of citizens throughout Europe more sustainable and less environmentally damaging.

The 'Blue Economy' not only focuses on reducing pollution and more sustainable exploitation of the seas in the long term, but also offers enormous potential for economic and job growth for all European citizens. Already 4.5 million people on the Continent are engaged in it, and much more work could come.

Napoleon Bonaparte, often also referred to as Napoleon, was a French politician and general, founder of the First French Empire and protagonist of the first phase of contemporary European history, known as the 'Napoleonic Age'.

His conquests throughout Europe and beyond make him one of the finest military strategists ever, but his importance is not limited only to victories in the field. Also important were some campaigns, such as the one in Egypt, which returned priceless treasures to the world. 

His life, studded with continual ups and downs, intrigues, murders and love affairs, ended in 1821 on the island of St Helena, in exile, due to stomach cancer. Although his life has filled the history books for over a century, some curiosities may still have escaped you.

There are many rankings that suggest which are the best countries in the world to live in. However, if you have children in tow, the factors to consider are probably very different.

In any case, they can already be a very good general indicator useful for families who want to expatriate or change countries to live in.
