I suspect we, humans have something in common with the bears. As we know, they hibernate themselves in the wintertime.
I like sleeping in fresh air that's why I always keep my window opened from and until the temperature outside makes it possible. But I finally closed the window in my room a week ago because it has got too cold outside. And since then, getting up at half past five requires much more effort.
I can feel the dawn coming when the window is opened. In that period of the year, I'm awake already when it's time to leave the bed. Thus I don't have to set the alarm clock. But if I sleep in darkness and in still air, I feel like it's the middle of the night when the alarm clock starts to ring. I think it's a common trait with the bears because my body remembers about things on an evolutionary scale of time. It believes I have less time to act in this season and it tries to save energy for me.
I have made another interesting observation. (or, at least, I find it remarkable on my part) Plastics are artificial material. Therefore it makes an unfamiliar impression on an almost unperceivable scale*. This is the reason why I rather drink from a glass glass or a ceramic jar than from a plastic glass.
It was my dog who enlightened me about this. He got a new pottery to drink water from and he certainly loves it because he still has his former plastic bowl and he hasn't drunk from that since then. And I realized this is a common trait of us.
Yesterday, my boss asked me to introduce what we had done in the spring to two people of my colleagues. One of them had taught me the Polyspace last week. So, we changed roles and this time, I was the instructor. And I had to realize it's not an easy trade. I realized that I just can't explain even simple things easily. Although they said in the end that my presentation was comprehensible, I'm afraid they were just polite. But today, I was asked to guess exercises for programming in Perl and this program was much better. But however, it was very absurd that one of my apprentices is much more qualified than me and at the same time, I gave instructions to him.
By the way, he's an interesting person. He speaks with a funny accent and I often don't understand him although he doesn't speak in a low voice. I haven't asked him yet because it would be impolite but I suspect he's from Slovakia because I had a colleague at my previous job and their accents are similar. Nobody has difficulties with communicating with him but me. I'm afraid this problem has something to do with the fact that I'm in deep water when I have to understand foreign talk. It's not my ears to blame because the problem is not the volume.
At lunch break, I was at the dentist's. Some years ago, I had a dental treatment by a quack doctor. Although her prices wasn't cheap, she cheated me many times and I get to know that in these days. For example, once I asked her to replace my amalgam fillings by white fillings. And as my present doctor was drilling my tooth and I was gargling, it turned out that my former doctor had left a large amount of amalgam in my teeth. She had covered just the top of my teeth with white fillings. And she had bungled many other things, as well. For instance, she used much more cement than what it would have been reasonable. And so on. But fortunately, my teeth has been recovering. Even though my dentist has just been on maternity leave but her substitute is also very trustworthy, considerate and professional. The prices are quite high here but the result is worth its weight in gold. Before my present doctor, I had only bad experiences with dentists. Once we had to endure dental treatment in the primary school. And that doctor didn't anaesthetize and drilled two teeth of mine in this way! That bastard! My clothes were very humid and I was trembling after the "treatment" for a long while. And the suffering was utterly futile as one of those teeth had to be pulled out later.
I will not change my present dentist, not for all the tea in China.

"Material sciences are pouring tens of thousands of artifical materials. The globality penetrates into the deepest levels of the matter's organizations and tears up the shells that protect these levels, with a brutal impulse. Dangerousness of artificial materials (and in this terminology, the nuclear bomb that uses the nuclear fission principle, as well as the peacefully used nuclear reactor’s fuel and combustion production, are also artificial materials) increases with an unbelievable speed. The more violent tearing-up of the existence-levels' protective shells is, the more risky energy there will be needed for these interventions. On the other side, nature (the real reality) does simply not recognize these materials, so it can't take back them into its eternal cycle.
(...)
Similiar phenomenons are developing on another field, where the titan of the globality is tearing up the code of life like a genetic hacker. Mankind is about to trespass further boundaries by creating genetically modified living organisms with a roughly similiar prudentiality that we can see in the case of the artificial materials. (By the way, GM organisms can also be qualified as artifical entities, since the main point is the same: tearing up the protective shell of existence before becoming aware of the real nature of the processes.)
The so-called genetic engineering gets stranger genes to a living organism even though it's not known exactly where the given gene-sequence will infiltrate although it really does matter. Various results may occur depending on where the artificially introduced element arrives at. The other grim phase is the fact that a gene-sequence is never active permanently in the nature. That is to say, a yet unknown mechanism is activated in one case only: when it's needed by the whole organism. With a violent intervention, all introduced genes are active all the time. As this has never happened in the billion years old history of evolution; we can only make guesses what the possible consequences will be. Until now, crucial majority of genetical mass was thought to be a redundancy or an overinsurance. It's unfolding in these days that this silent depth, in other words, the majority of the mass is, in fact, a complex system of a sophisticated regulation operated by yet completely unknown mechanisms.
All GM living things are biological time bombs and we have no idea about their timing. We can only hope that it won't get working at a time and a place, when and where we expect the devastating consequences at the least.
And this is only the inside of the processes. In connection with outside effects, it's utterly unclarified, what consequences can break loose during interactions between GM and non-GM living beings and how the spontaneous interbreeding of perpetuating materials can alter complete living spaces or what's more, the entire ecosytem, as a chain reaction. It's also not clear how living organisms that eat manipulated living things, will react to all of this."
