- It happens the same everywhere around the world. (The Yard)

-I was invited somwhere in the wold, by a friend, my friend make a lot of promisses. Promises which prefer to forget, now. He live in a house with several apartaments, with a shared courtyard. Since I am hosted here, and waith the promises come true, I see the same general dirt in the yard. - Time passes by working better. I said, and I grabbed with enthusiasm to clean. Gathering dried laves, collecting papers, sweep. A Lady , neighbour Lady, asked me, very surprised what I doing there . - Cleaning the yadr. I answered. - Because we get a lot of dirt in the house. - Yes she sayd. And she explained that the man who is responsable with cleaning dose not do his job. The inhabitants of the house will make a meeting, and they will solve the problem. This very ugly problem . - OK. I said, she left. While I cleaning the yard, I think what will happen now ? The man will be judjed, they will fire him . However, it is his duty. Or not ? I have collected numerous remnants of cigarettes, Ice cream papers, ...... Did we not have to respect the work of others ? - I asked myself. Why ?. 

- Maybe the man can not chase after everyone. And it looked like in the yard, is a competition. - Who throw more rubbish. It is easy to criticize, it is harder to help. For example: - do not throw trash in the yard. But, it is easier to judge . - This happen every day wherever in the world. We are different characters, but the same different caracters live worldwide, the only thing that is different is the country in which we live. Or where we come from. Richer country , or a poorer country. And it's good, they are poor countries, - We have forgotten how cleaning. They will do it. While I was cleaning, listening the album, The Wall (Pink Floyd and it fit well in the current situation.) I just remembered, my friend promises . - " Our home , our food , our work , life together ........." Yeah sure . Now my friend says he promised to much. In other words . Get out. Or , I 'm bored with this new toy. Thank God that we are not all the same. We are different characters. I have favorite quotes : - "Accept the things to Which fate binds you, and love the people with Whom fate brings you together , but do so with all your heart . " .... "Where I live if someone Gives you a hug it's from the heart . "...To tell the truth, I was very well tolerated in this house, I did not missed anything, for a time. Now my days are counted here, I think I've become an unwanted ghost. A sort trash. Why people do not understand, that promises must be respected. As a man's life may depend on promises. Those who are educated in the virtual world, forget the true world. - "Love all, trust a few, do wrong to none." - - I do not want to hurt anyone, especially my friends, my friend. I keep the pleasant memories. (Because it was. I was accepted and helped for a while. I must admit that. ) My friend wants to help me, even now. He'll tolerate my presence in the area. What great luck I have. Stupidity and reign are paid. I feel it now. - I continue to clean away, maybe I'll manage to clean, in my soul and in others soul. Maybe. But life will never forgive this fatal mistake, why I trusted my friend. Why ? - Because things are linked together, promise and trust. Okay, time to go, I do not accept any false help, and promises more. I'm going to clean in to another world.

Efectele adverse ale ecranelor asupra somnului pot fi ''uşor de inversat'' (studiu)
 

Efectele nocive ale luminii albastre emisă de ecrane sunt ''uşor de inversat'' după o perioadă de ''detoxificare'', conform rezultatelor unui experiment prezentat duminică de cercetători din Olanda, citat de Inverse.

Expunerea la dispozitive electronice în timpul serii ''poate tulbura somnul'', parţial din cauza luminii albastre emise de ecranele cu LED-uri, precum cele ale tabletelor, telefoanelor mobile şi computerelor, potrivit American Academy of Pediatrics. Unul dintre motivele pentru care acest lucru se întâmplă este faptul că lumina albastră poate suprima eliberarea melatoninei, hormonul ce reglează ciclul somnului.

Studiul recent, condus de cercetătorul Dirk Jan Stenvers de la Universitatea din Amsterdam, alături de Institutul naţional olandez pentru sănătate publică şi mediu, a demonstrat că lumina albastră a afectat somnul în cazul a 25 de tineri care utilizau ''frecvent'' ecranele. Stenvers a descoperit că, din fericire, efectele nocive pot fi reversibile.

''Adolescenţii dedică din ce în ce mai mult timp dispozitivelor cu ecrane, iar neplăcerile asociate somnului sunt frecvente la această grupă de vârstă'', a explicat Stenvers duminică, în timpul prezentării susţinute la conferinţa Societăţii Europene de Endocrinologie, organizată în Lyon, Franţa.

''Demonstrăm aici faptul că aceste neplăceri asociate somnului pot fi uşor de inversat prin restricţionarea utilizării ecranelor sau a expunerii la lumină albastră în timpul serii'', a notat specialistul.

Stenvers a condus timp de cinci săptămâni un experiment la care au participat 55 de tineri din Olanda - 25 de utilizatori ''frecvenţi'' ai ecranelor, respectiv cel puţin patru ore pe zi, şi 30 care foloseau mai rar dispozitive cu ecrane, circa o oră pe zi. În această perioadă, fiecare grup a renunţat pentru o săptămână la utilizarea ecranelor în timpul serii. Ulterior, subiecţii au purtat ochelari speciali, cu filtru de protecţie împotriva luminii albastre.

În medie, utilizatorii frecvenţi aveau nevoie de 30 de minute în plus pentru a adormi şi tot ei au raportat mai multe neplăceri în timpul nopţii. Însă, după şase nopţi de abstinenţă de la ecrane sau de utilizare a ochelarilor speciali, somnul lor a început să fie similar cu cel al persoanelor care utilizau mai rar dispozitivele cu ecrane. Aşadar, "detoxificarea" de la lumina albastră s-a dovedit utilă.

Utilizatorii frecvenţi care au apelat fie la purtarea ochelarilor speciali, fie la abstinenţa de la ecrane au reuşit să adoarmă, în medie, cu 20 de minute mai repede şi să se trezească cu 20 de minute mai târziu. ''Ambele intervenţii au restabilit perioadele de somn ale utilizatorilor frecvenţi'', au notat autorii cercetării.
