Why, sir, are some more motivated than others?

Let’s take a classic case! The new year has begun, you have to go to work with love, and you just noticed that the holidays left an impression on you in the form of extra buns. Well, what will colleagues say? That you are some kind of blabbermouth who can’t resist insults and shrugs? It’s not done. So you sign up for a gym membership, vow to look better than the Olympian gods in six months, and get down to business.

After about a week or two, you’ve also taken the gym like sour apples and think that if someone likes you, they like you the way you are, more lustful. Well, what about a bitter life? So much for motivation. Instead, you watch others stretch like desperadoes and count their stomach squares more like a chessboard. How do they, sir, manage to find motivation? Well, that’s science… no kidding.

Several scholars explain this. More precisely, it is about how everyone’s brain works. Let me explain! It’s all about chemistry. For example, with the help of a neurotransmitter called dopamine. You have heard of it, it is also called the hormone of happiness.

Well, multi-subject studies have shown that dopamine is released differently in some people when it comes to activities like the ones mentioned above and others where it’s effort + reward. Some have higher amounts of dopamine in the cerebral cortex, which is responsible for motivation and the desire to receive a reward. In others, it mainly stands out in the area related to emotions and risk perception.

In short, it motivates some to act towards their goals, i.e. reward. Others less. That’s it, the brain is to blame. Here you need to work with him, take him to a personal conversation and convince him that a simple desire to do or get something is not enough. “Bone to work” should also be launched. That’s all. The case is solved!

Stress can have unexpected effects on memory

Being under stress is quite unpleasant, we all know it. Please, I bombarded you with this information, but it wasn’t about her, it was about a small detail related to stress and how it can help your short term memory. It would be beneficial even in small doses.

So claim some researchers from the University of Georgia, USA, who tested several volunteers (about 1200) to see how stress affects their cognitive abilities. To do this, they gave them a questionnaire where they had to remember something similar to memory.

It turned out that those who are under a lot of stress still forget from hand to mouth. In contrast, those with moderate/low levels of stress showed improved short-term memory. Apparently, they showed the best results in the mentioned tests. By the way, it was the same with mice. Same results.

In closing, we can only give you the most useless advice…stop stressing so much that you forget what you read here! Take it easy, it’s better! This is it!

What did humans have with bears over 300,000 years ago?

If they had something personal, we cannot know and will never know. The novelty, if you can call it that, comes from the German site of Schöningen, where the oldest set of complete spears, more than 300,000 years old, was discovered many years ago. The fact is that recent excavations have revealed cave bear phalanges that show atypical incisions in the sense that they do not appear to have been made for the purpose of extracting muscle tissue.

Basically, you don’t have much muscle tissue from the phalanges of a bear. By comparing specimens with well-known relatively recent periods, it was concluded that the corresponding incisions, short and extremely precise, were made to cut and remove the animal’s fur. In short, these individuals used cave bear fur to create, most likely, clothing, about 320,000 years ago.

Now, this discovery is not a big discovery. No one would think that prehistoric individuals run around in open areas like the Yeti – the Abominable Snowman. It is true, the people in question lived during the Mindel-Riss interglacial period, that is, a warm period similar to the present. Even so, it was still cold in winter, their teeth were chattering in their mouths, and we would have found them all grinning in the permafrost like mammoths if they hadn’t made clothes too.

The novelty comes from the evidence of the fur collection, the said discovery is the oldest of its kind in the world. As for the Pleistocene relationship between man and bear, rest assured, there are sites all over Europe from Georgia to the Atlantic that show the cave bear was constantly hunted. There is even evidence of the existence of communities that specialized in this type of hunting. And no, we are not necessarily talking about Homo sapiens, but, in particular, about the Neanderthal.
