One of those big social networking sites, Facebook, has attracted over 58 million members. Commentator Melody Cramer is no longer one of them. Here is what she shares with us about her story.

I deleted all 1,281 of my co?workers, second?grade classmates and people who I don’t know at all. I shut down my account, completely. I’m 30, and I’ve been on Facebook since March of 2004, which makes me one of the website’s earliest users.

At first, I used it obsessively. If I had a free moment, I’d log on to see whether my friends had updated their profiles. I’d sit alone scrolling through these updates and then run into someone at a coffee shop and have nothing to say because I already knew everything about them, and they knew everything about me.

In November, I went to my ten?year high school reunion and was not pleasantly surprised. Lauren became a model, Josh went to law school, Dina was a teacher. I hadn’t talked to any of them since graduation, but I knew exactly what they were doing, both now and last week. But lately, I’m overwhelmed(应接不暇). Facebook opened up to everyone, not just college students, and my co?workers started to join, which meant they now knew what I was doing when I wasn’t at work.

And as a rule: you can NOT make friends with your coworkers because then they’ll ask you the next day. But I thought we were friends. And you are friends but not the kind of friends who tell each other what they do outside of work. So now the people you work with can see what you did last night, and you’re constantly worrying what people might say about what you did last night instead of actually doing anything tonight. So Iquit. I became a 30?year?old Luddite, a person who is strongly against technology development. I’ve retuned to how the world worked when I was 20, before I knew when my friends and co?workers were counting down the seconds to vacation or entering a complicated relationship. I’m hoping life will be a lot simpler now. People will be more mysterious now that I actually have to talk to them to find out their favorite books or hobbies or neurosis(神经症). I don’t know when my college roommate goes to the supermarket, and I think I’m a better person for not knowing. In fact, you could say getting off a social network was the best thing I’ve done this week.

Why are people interested in eating raw foods or whole foods? One reason is that eating these types of food reduces the risk of acid accumulation in your body. Raw and whole foods are usually digested more efficiently than cooked and refined foods.

When we cook foods,we destroy the natural enzymes(酶)that are part of the food in its raw form.These enzymes were intended by nature to help us digest the food.When we consume food without these natural enzymes,our bodies either digest the food improperly or allow too many nutrients to be absorbed into the bloodstream.In both instances,the result is obesity.When too many nutrients are absorbed at once,the body grows fat.

Processed foods contain chemical elements,which might confuse the appetite mechanism that tells us when we’ve had enough to eat;as a result,people often overeat.Processed foods also upset the digestive cycle.The body will either identify these foods as allergens(过敏原)and then store them safely away from the organs as fat,or the remains of undigested food will become acidic and enter the bloodstream as acid waste,which will stick to the blood vessel walls and block the passage of vital oxygen and nutrients heading for the body's cells.The body's metabolism(新陈代谢)becomes inactive,and the result is weight gain and obesity.

To stop this vicious circle in its tracks,people need to consume food and supplements that will neutralize the acid already accumulated in body.Eating the right types of raw and whole foods can help.It’s also important to restore your enzyme balance.You need to identify and avoid the foods that cause acid accumulation and consume the foods that increase enzyme production.If you truly want to change and help your body heal itself,you need to take an active approach.
