2 . I used to be anorexic (厌食的). I was skeletal, each of my rib bones jutted out, like ridges on my body; my head, which looked abnormally huge, was barely supported by my backbone.
It would take an hour for me to eat a spoon of food. Should I attempt to eat to please my parents on teachers, I would lock myself in the toilet and throw up the food. I looked pale and weak all the time because of the lack of food. My family members were distressed. They cried a lot.
It all started when a boy in my class called me “fat” I was devastated. I adopted an extremely strict diet and exercise routine. I lost 10kg within three months and continued to lose more weight. I was absolutely obsessed about losing even more weight. One day, my heart rate dropped and I was breathless. I almost lost my life. That was when I decided to turn my life around.
Looking good is extremely important to a teenager. We want to look a certain way so we can be popular and accepted. We are attracted by well-toned and sculpted bodies. Now, with social media, we have access to a pool of photographs of people, whose bodies and appearances we admire. Those images make us envious. We long to be like them.
We're in danger when we start to hate the way we look and take drastic measures to attain the body we dream of having. These measures can lead to eating disorders, unrealistic and unhealthy exercise habits, low self-esteem and depression. Besides affecting the physical health, teenagers who are body conscious can also suffer from mental instability. They may plunge into despair, guilt and hopelessness if they are unable to keep up with their rigid exercise routines or eating habits. They can be emotionally fragile too. They become sensitive to comments made by others. They are ashamed of the way they look. If you are currently experiencing these feelings, seek help before itis too late.
It is important to feel confident and positive about your image and not subscribe to man-made standards of beauty, which will change with time. You are unique.

3 . Medicine is not exclusively a human invention. Many other animals, from insects to birds to nonhuman primates, have been known to self-medicate with plants and minerals for infections and other conditions.
Behavioral ecologist Helen Morrogh-Bernard of the Borneo Nature Foundation has spent decades studying the island’s orangutans (猩猩) and says she has now found evidence they use plants in a previously unseen medicinal way.
During more than 20, 000 hours of formal observation, Morrogh-Bernard and her colleagues watched 10 orangutans occasionally chew a particular plant (which is not part of their normal diet) into a foamy lather (泡沫) and then rub it into their fur. The apes spent up to 45 minutes at a time massaging the mixture onto their upper arms or legs. The researchers believe this behavior is the first known example of a nonhuman animal using a topical painkiller.
Local people use the same plant Dracaena cantleyi, an unremarkable-looking plant with stalked leaves-to treat aches and pains. Morrogh-Bernard’s co-authors studied its chemistry. They added extracts (提出物) from the plant to human cells that had been grown in a dish and had been artificially stimulated to produce cytokines, an immune system response that causes inflammation (炎症) and discomfort. The plant extract reduced the production of several types of cytokines, the scientists reported the finding in a study published last November in Scientific Reports.
The results suggest that orangutans use the plant to reduce inflammation and treat pam. Such findings could help identify plants and chemicals that might be useful for human medications.
In creatures such as insects, the ability to self-medicate is almost certainly innate: woolly bear caterpillars infected with flies seek out and eat plant substances that are poisonous to the flies. But more complex animals may learn such tricks after an initial discovery by one member of their group.
For example, an orangutan may have rubbed the plant on its skin to try to treat parasites and realized that it also had a pleasant pain-killing effect. That behavior may then have been passed on to other orangutans. Because this type of-self-medication is seen only in south-central Borneo, Morrogh-Bernard says, it was probably learned locally.
