Ada beberapa hal yang sering dilewatkan dalam menjalani hidup, sehingga akibat buruk dari kebiasaan ini akan datang mengganggu kesehatan kita. Hal ini bisa terjadi hanya karena kebiasaan hidup yang tidak teratur. Kebiasaan tersebut adalah antara lain melewatkan sarapan, kurang minum air putih, kurang gerak sampai dengan ngemil snack berkalori tinggi.
Menurut Pete Cohen, psikolog dan physical trainer, bahwa tidak ada manusia lahir dengan kebiasaan buruk. Kebiasaan ini dipelajari saat tumbuh dewasa. Cara yang paling jitu untuk membuang kebiasaan buruk adalah dengan menggantinya dengan kebiasaan yang lebih baik. Menurut beberapa penelitian, diperlukan pengulangan 20 - 30 kali untuk kemudian menjadi kebiasaan baru.
Apakah semudah itu ??, sepertinya mudah saja, tapi kalau dijalani mengapa sulit??, karena kita memang hidup dilingkungan yang sudah mengesahkan kebiasaan-kebiasaan buruk itu menjadi hal yang biasa.
Ada beberapa tips dibawah ini, mengenai cara menghargai hidup dengan menjalani hidup secara sehat dan teratur, yaitu:
1. Minum air putih secara cukup
Kenapa terjadi? tubuh manusia tidak akan memberi sinyal berupa rasa haus sampai tubuh benar-benar kekurangan air atau mengalami dehidrasi.
Mengapa air putih? karena dua per tiga tubuh kita terdiri dari air, maka air merupakan unsur terpenting bagi tubuh. Setiap hari kita kehilangan 1,5 liter air lewat kulit, paru-paru dan ginjal (berupa air kencing). Untuk itu kehilangan itu harus digantikan dengan jumlah yang cukup, sehingga tubuh akan terhindar dari kelelahan, sakit kepala, kulit kusam dan bad mood.
2. Sarapan pagi setiap hari
Kenapa terjadi? Alasan yang sering didengar adalah karena tidak cukup waktu untuk sarapan.
Mengapa sarapan? Kalau sarapan terlewatkan maka akan mempengaruhi produktivitas kerja. Untuk itu 'dengarkan' tubuh anda dengan melakukan sarapan sehat secara rutin setiap hari. Sarapan sehat adalah makanan ringan yang cukup gizi seperti segelas susu atau jus buah atau sarapan siap saji yang kaya gizi dan rendah lemak.
3. Makan siang yang bergizi
Kenapa terjadi? Karena biasanya kelebihan karbohidrat sering terjadi saat makan siang, atau kurang mengkonsumsi makanan yang mengandung protein sebagau sumber energi.
Mengapa harus bergizi? Biasanya ngemil makanan tinggi kalori akan jadi pilihan utama apabila rasa lapar menyerang, seperti cokelat, keripik atau biskuit, yang banyak mengandung lemak, gula dan garam.
Untuk itu memilih makan siang yang bergizi adalah cara yang bijaksana untuk mengatasi rasa lapar. Cara yang bijaksana menurut Dr. Wendy Doyle, ahli diet, dengan cara menambah lauknya, makan sepotong buah atau segelas yoghurt.
4. Siasati makan malam
Kenapa terjadi? Biasanya setelah lelah seharian kerja, maka akan malas kalau harus mempersiapkan makan malam.
Mengapa disiasati? Karena biasanya bila tidak mempersiapkan makan malam maka fast food atau take-away food, yang pasti mengandung tinggi lemak dan garam. Cara mengatasinya??, makan sesuatu sebelum pulang kantor dan mengisi kulkas dengan bahan makanan yang lebih tahan lama simpan untuk keadaan darurat. Kalau terpaksa membeli makanan, lebih baik hindari makanan yang digoreng dan pikirkan makanan tersebut mengandung gizi, yang paling tidak, cukup.

Bisa beli PDF-nya, Pak?
Format dokumen PDF pertama kali dikenalkan oleh Adobe System (http://www.adobe.com), hasil dari pengembangan Dr. John Warnock di awal tahun 90-an. Proyek PDF dimaksudkan membuat format file untuk distribusi dokumen di dalam perusahaan yang dapat ditampilkan di berbagai platform komputasi.
PDF akhirnya menjadi format dokumen yang universal dan lintas platform, karena tersedia di berbagai platform komputasi. Program untuk membaca dokumen PDF dalam berbagai platform disediakan secara gratis untuk didownload oleh Adobe System. Plug-in program pembaca untuk browser populer juga tersedia, sehingga dokumen PDF dapat dibaca langsung secara online dari situs internet tanpa perlu mendownload dokumen dan membacanya denga program yang terpisah dari browser web.
PDF memiliki beberapa fitur keunggulan antara lain:
- Universal dan Lintas Platform.
Dokumen PDF dapat dibaca di berbagai platform, bahkan dapat dibaca secara online melalui browser yang telah dilengkapi dengan plug-in pembaca PDF. Tools dan printer driver untuk membuat dokumen PDF pun banyak tersedia. Keunggulan ini menyebabkan dokumen PDF dapat digunakan secara luas di seluruh dunia. - Yang Anda Lihat, Yang Anda Dapatkan.
Berbeda dengan format HTML/SGML, PDF lebih dapat menjamin apa yang ditampilkan pada monitor, maka serupa itu pula yang akan kita dapatkan jika dokumen dicetak. Dengan format HTML/SGML, maka hasil cetakan bisa jadi akan berbeda dengan yang tampak di monitor, bahkan dokumen yang tampak di monitor pun bisa jadi berbeda-beda tergantung dari browser yang digunakan. Hasilnya, PDF sangat sesuai digunakan untuk menampilkan informasi kritis yang tidak memperbolehkan variasi dalam presentasinya, misalnya invoice, tanda terima, dan laporan-laporan baku lainnya. - Hemat Ukurannya.
Secara native file PDF telah dikompresi sedemikian rupa, sehingga ukuran filenya akan lebih kecil daripada jika file tersebut dalam format HTML, misalnya. Kecilnya ukuran file PDF ini menyebabkan PDF populer digunakan untuk tukar-menukar dokumen lewat internet karena tidak memboroskan bandwidth data. - Pengamanan Dokumen Dapat Diandalkan.
PDF juga memiliki fitur pengamanan dokumen dari kemungkinan pencurian isi, duplikasi, dan pencetakan dokumen oleh yang tidak berhak. Sebuah dokumen PDF dapat pula diberikan tanda tangan digital (digital signature) sehingga penyebaran dokumen dapat lebih dikendalikan. Fitur ini tidak dimiliki oleh format dokumen universal seperti HTML/SGML.
Benarkah Perlu PDF?
Kecuali jika Anda hanya ingin bekerja dengan dokumen-dokumen non presisi dan tidak menginginkan kemudahan bertukar dokumen, maka Anda kemungkinan besar membutuhkan format dokumen PDF.
Jika Anda ingin:
- membuat invoice, order pembelian, surat pengangkutan, tanda terima, dan dokumen komersial untuk situs e-commerce atau aplikasi berbasis web
- membuat laporan dari aplikasi berbasis web dengan format yang presisi yang tidak memperkenankan variasi hasil cetakan
- membuat cetakan form isian dari web dengan hasil yang seragam
- membuat dokumen lain yang membutuhkan pengendalian baik terhadap distribusi dokumen maupun presisi dan kualitas cetakan, serta dapat dipertukarkan secara mudah,

China restructures mobile market ready for 3G force
SHANGHAI, China (CNN) -- When Shi Rui Huan was led through the back entrance of a China Mobile store on the first day of April last year, he had no idea that he was about to be at the center of one of the most significant events in the history of telecommunications in China.
Shi Rui Huan, aka, 'the 3G guy' shows off his 3G phone. Will millions of other Chinese follow his lead?
And he also had no idea that he had just become the victim of the ultimate April Fool's joke. One of his friends had called the day before, told him there was an important meeting he should attend and to be sure to dress up.
It turned out that Shi had been chosen to be the very first person to have the very first subscription ever given out in China for third-generation (3G) mobile phone service. His face appeared in newspapers and on television programs for weeks. Even today he's still known by many as simply "the 3G guy."
"It was like I was like President Hu Jintao," Shi said jokingly.
Shi, a trendy, 31-year-old who works in advertising and can often be spotted wearing his favorite pair of black cowboy boots while smoking gold-tipped cigarettes, is exactly the type of customer China's mobile phone operators are hoping will be among the first to subscribe for 3G services.
First introduced in Japan a decade ago, 3G wireless networks give subscribers faster Internet connections, which means music, movies and games can be downloaded with greater ease, e-mail can be accessed much more quickly and other multimedia applications such as instant messaging and video-conferencing are possible on a mobile phone.
After a slow start, 3G is now widely used in Japan and Korea, yet has had less than stellar adoption rates across Europe and in the United States, where uptake has been stymied because of expensive handsets and pricing plans, poor network coverage and lack of consumer interest.
For years, Beijing has delayed the rollout of next-generation networks largely to complete technology for its homegrown 3G standard called TD-SCDMA, which many experts say was developed to reduce China's dependence on foreign technology and spur the growth of its domestic telecom industry.
Last spring, the government began testing the new standard among select customers -- Shi was the first -- in a handful of cities and last month announced it would issue 3G licenses to the country's three state-owned mobile phone carriers. China Mobile, the dominant provider by far, received the license for TD-SCDMA, while China Unicom and China Telecom were given licenses for international standards used in Europe and the United States.
The carriers have announced they will collectively spend almost $60 billion over the next several years to build their respective 3G networks while the government has set targets for tens of millions of subscribers by 2011.
The billion-dollar question
Now that the guessing game surrounding when China would finally issue 3G licenses has ended, many experts are wondering exactly what, if any, impact next-generation networks will have in the biggest mobile phone market in the world.
"That is a million-dollar question," said Benjamin Joffe, founder of the Beijing-based mobile and Internet consulting firm Plus8Star. "Essentially if you want to know how a market with 10 years experience is doing, the simplest thing to do is to look at Japan."
While some say the success of 3G in Japan is mostly hype, the country, which has over 80 percent adoption rates, has become home to a "thriving mobile ecosystem," said Joffe, noting that second-generation (2G) handsets are no longer sold there.
Two of the richest mobile social networking companies in the world are based in Japan, along with a number of other highly profitable firms that have developed cool content and even cooler applications, such as mobile commerce and mobile auctions, for 3G phones.
Similar businesses have begun to emerge in China and are creating mobile platforms aimed at the country's technologically savvy youth, hungry for entertainment on-the-go and turned on by flashy 3G phones.
"It is very good for us," said Alvin Wang Graylin, whose Shanghai-based mobile search and ad provider mInfo is positioned to directly benefit from 3G's higher data speeds. "[Subscribers] will use more mobile Internet and more mobile data services, leading to more ad inventory," he said.
According to Frost & Sullivan's senior industry analyst Marc Einstein, even without 3G networks Chinese telecoms already earn over 20 percent of their revenues from non-voice data usage, like text messages and ringtone downloads, which is on par with carriers in the United States where high-speed networks have been in place for years.
"I think this bodes well for future uptake in the market," said Einstein. "China is leaps and bounds ahead of most other emerging markets, notably India where the figure is more like 10 percent."
However unlike 3G users in other markets, those in China have considerably less cash, which means its widespread adoption may boil down to one thing: cost. In a country where the average per capita income is only a few thousand dollars a year, next-generation wireless service may be prohibitive for a while.
"In terms of immediate impact on the market, it is going to be very limited just like it was in any other country that launched 3G -- in the first two years, nothing happened," said Joffe. "There won't be miracles."
Power of the Chinese consumer
But if prices are affordable, especially on the handset side, some believe the demand for 3G may be driven by consumers in second- and third-tier cities which simply want to log onto the web.
"Pure Internet usage will be a strong driver," Nokia spokesman Thomas Jonsson told CNN. "Today there is already a very high number of Internet users and the first time they enter the Internet is through their mobile phones."
And also for the first time, consumers may have more power than ever to shape the state-controlled telecommunications industry, which was restructured last year to pave the way for 3G and introduce more competition.
Faced with China Mobile's unproved TD-SCDMA network that works mainly with less-than-fashionable handsets from domestic companies, many Chinese may choose to switch the other carriers that have tried-and-tested 3G standards and are compatible with brand name handsets from foreign manufacturers.
"I think consumers will ultimately be smart, and that is a challenge for China Mobile," Duncan Clark, chairman of consulting firm BDA China, told CNN.
"There is a good market in China," added Clark. "Chinese like to adopt technologies and show them off."
Shi, who switches mobile phones at least twice a year, says he already is on the lookout for the next cool handset to flash around in front of his friends. Yet when it comes to talking about being the first-ever 3G subscriber in China, he is slightly less exuberant.
"It is not a very important thing in my life," he said while smoking one of his golden cigarettes and sipping tea. "It was just a joke."from : http://edition.cnn.com/2009/TECH/01/27/db.china3g/index.html
