What do crabs eat?

Went to crabbing with some friends a few days ago, but unfortunately we didn't catch any crab, but a tiny weenee baby crab wondering in the net that we had to let go. So, there was nothing much to blog about that, except for beautiful scenary, strong wind, other fisher and jetty that was filled with dried fish bone and ralae. Kinda messy actually.

But the topic "what do crabs eat" came up on the dinner table. Between, we use kangaroo back bone as the bail for crabbing.

C:"There is no kangaroo in the sea, that is why crab don't eat them...., may be we should use dead rotten fish....."

W:"But some fishes may eat crab, so what kind of fish should we use?"

I: "May be we should ask the fishmonger, they must know? "

Here is the result from a search on the internet

"Crab are scavengers and usually eat dead matter and algae. Some crabs will take eat living animals like shrimps, small fish and snails."

Hence, the conclusion is crab eat dead matter, i think any junk will attrack them if they are in the mood of eating and being catched. Aw, i am craving for crab after the dissapointing crabbing trip. Miss my mum's chilli crab so much now, , can't wait till 3rd of dec.

无知是幸福的

在书上读的疾病,癌症,死亡等等等等,
我真的以为这些都是书上的资料和"别人"的遭遇,
是我知道的比较多了, 还是"坏"的频率提高了?
好象我所读所闻都渐渐出现,老实说:我一点都不喜欢这一种感觉;

在desperate housewife里, Susan说了一句"everyone got cut up everyday, i think i can handle it." 这一句话被我消化成,这世上天天都有人被割(开刀),可是我还是不想被割. 我想每个人的心灵深处都会有恐惧的一处,至少我有.

在别人有伤心事的时候,那些可以触动心灵的话语,其实对自己是没有什麽作用的. 再次证明"针不刺到肉是不会痛的",我好象懂了.

好象无知才是最幸福的,我还可以吗?

Coffee and Honey

Have you ever hate drinking coffee due to the sour taste?
I have just figured out that mixing coffee with honey will eliminate the sour taste and make the bevarage perfect to drink. Well, i am not sure if every type of honey works, i use manuka honey. :)

responsibility and obligation

Responsibility is defined as a duty to deal with or take care of somebody
or something, so that you may be blamed if somthing goes wrong.

Obligation is defined as the state of being forced to do something because
it is your duty, or because of law; or something that you have to do because you have promised or because of law.

Mandatory is defined as something you must do as required by law

I used to think that we have a choice to choose and decide what is our obligation. However, it turns out that life is much more complicated. Sometimes, obligation is not optional, it is the same as responsibility and mandatory.

Butterfly Effect-蝴蝶效应

我自创的formula

Wilkepedia 很清楚的解释,

The butterfly effect is a phrase that encapsulates the more technical notion of
sensitive dependence on initial conditions in chaos theory. Small
variations of the initial condition of a dynamical system may
produce large variations in the long term behavior of the system. This is
sometimes presented as esoteric behavior, but can be exhibited by very
simple
systems: for example, a ball placed at the crest of a hill might roll
into any
of several valleys depending on slight differences in initial
position.
The
phrase refers to the idea that a butterfly's wings might create
tiny changes in the atmosphere that ultimately cause a tornado to
appear (or, for that matter, prevent a tornado from appearing). The flapping
wing represents a small change in the initial condition of the system, which
causes a chain of events leading to large-scale phenomena. Had the butterfly
not
flapped its wings, the trajectory of the system might have been vastly
different.

中文的解释为,

蝴蝶效应（Butterfly Effect）是指在一个动力系统中，初始条件下微小的变化能带动整个系统的长期的巨大的连锁反应。这是一种混沌现象。
美国气象学家爱德华·罗伦兹（Edward
Lorenz）1963年在一篇提交纽约科学院的论文中分析了这个效应。“一个气象学家提及，如果这个理论被证明正确，一个海鸥扇动翅膀足以永远改变天气变化。”在以后的演讲和论文中他用了更加有诗意的蝴蝶。对于这个效应最常见的阐述是“一个蝴蝶在巴西轻拍翅膀，可以导致一个月后德克萨斯州的一场龙卷风。”
蝴蝶效应通常用于天气，股票市场等在一定时段难于预测的比较复杂的系统中。
此效应说明，事物发展的结果，对初始条件具有极为敏感的依赖性，初始条件的极小偏差，将会引起结果的极大差异。
“蝴蝶效应”在社会学界用来说明：一个坏的微小的机制，如果不加以及时地引导、调节，会给社会带来非常大的危害，戏称为“龙卷风”或“风暴”；一个好的微小的机制，只要正确指引，经过一段时间的努力，将会产生轰动效应，或称为“革命”。

如果两个人的关系等于 A+B, 然后第三个人 C 加入, 结果并不等于 A+B+C, 而是等于 X (未知数). 原理很简单, 人际关系并不象数学, 加减乘除是不适用的. 写了那麽多, 也只不过是想说原来把一个人带入你的生活有时侯会给原本的生活带来很多改变. 当然不是完全不好, 不过不好的好象多过好的. 又发现我原来真的很笨. 笨蛋笨蛋.

用心聆听

有一天，有一个老人，在他家的仓库里寻找着一些东西。由于仓库里十分闷热，加上老人的脾气也不大好，所以找了好久才找到他要的东西。
但是当他从仓库里走出来之后，他却突然发现他心爱的怀表不见了！那可是他的传家之宝，也是他最心爱的宝贝！于是他立刻走回去仓库里面，在寻找的当中也不停的埋怨。最后他有找到吗？正确答案，是没有的。
他非常不开心的坐在仓库的门口不停的埋怨，突然老人的孙女走了过来：“爷爷，你在烦恼什么呀？”老人回答说：“可爱的孙女啊，爷爷的怀表掉在仓库里面了，爷爷找了好久都找不到哦。”孙女回答：“不用紧的爷爷，我可以帮你找！”说完就走进去仓库了。
不到几分钟的时间，孙女就拎着怀表走出来了。爷爷十分惊奇，问道：“宝贝孙女！我刚刚找了整个小时都没有找到，怎么你一下子就找到啦？”孙女笑笑回答说：“爷爷，我刚刚走进去仓库里面，我静下心来，用心聆听怀表所发出来的微小声音，过后就朝着声音的方向去找，就这样找到啦！”
这故事的启示给我很大的感受，因为我们生活在忙碌的都市中，许多时候都为工作或为生计而忙碌。或许目前有一份工作，但工作也不是那么的顺心；或许我们有一份收入，但只是供期就没剩下多少了；或许我有个家庭，但却每天奔波而缺乏时间与家人相聚。当人心情不好的时候，就会每天在抱怨这个抱怨那个。
我们何曾有一段时间，用心聆听自己心里面所发出来的声音？想看看，这份工作是不是自己当初所期待的？目前的生活是否应该交给自己安排？我是每天见老板的时间比和家人相处的时间还多？
到底自己要的是什么？目前的状况能够达成你要的目标吗？停止埋怨，用心聆听自己和别人心里面的那句话，找到自己心中宝贝的那只怀表。

abnormal "normalities"

There was time when i was away from family, living outside for the sake of study. Then, i got busy with study, friends and all other activities. 24 hours a day wasn't all that much when you have a lot of tasks to be accomplished. Then, i call home less and less. I used to think that it was okay to take a break from family, because they will always be there for you.

Turn out, i am wrong. Changes occur every seconds. Then, i know i shouldn't take things for granted. Guess i was trying to get away from the problems.

Just realise that all the subtle changes that have taken places to the people and places that used to be familiar to me have accumulated and become a tremendous change. How can i ever miss that?

I realise that i seem to be more and more invisible from their life. I don't really know how to readapt if i were to go back for good. More importantly, my parent are getting older and siblings are getting taller and more mature. And, i wasn't there for them when they need me. Don't know what i can do now, guess i can only go with the flow. Only do what i can right now.

Oh well, it is all about exam associated syndrome again.

Dental tips-Avulsion

I am writing this to share some of the informations i learn from paying thousands to the university. And, i think these informations will seriously help to increase the chance of saving your tooth and your smile. So, take a few minute to read.

Avulsion is one of the common injury that can happen to anyone, especialy someone who are actively involve in sport. Avulsion can also happen in trauma, accident, trip over and in the case when excessive force is applied to the tooth or chin. So, what is avulsion? Avulsion is the total displacement of tooth out of the socket. And, it is importance that you know how to handle the tooth when it is outside your mouth.

A tooth is held in the socket via some elastic connector that we call Periodontal Ligament (PDL) in Dentistry. PDL attach to tooth and socket surfaces that contain living cells that have repair ability. Avulsion leads to complete breakage of the PDL. That means if you insert the tooth back into the socket soon enough, your tooth may have a chance to live by repairing itself. But, the chance for your tooth to live goes down with increased age and time lapse after accident. For example, your top front teeth will have complete tooth and root formation at about 13 yo, if the accident happened before 13 yo, the chance for you to save your top front tooth is increased. In a mature tooth, the tooth will still have pretty good chance of serving its function with appropriate dental treatment, such as root canal treatment.

Ok, Let's talk about how to handle your tooth. As I mentioned above, the surface of the avulsed tooth has living cell and part of the PDL, it is essential to prevent touching the tooth surface with your contaminated hand. Hence, pick the tooth up at the crown (top part of the tooth that you usually see in your mouth).

Then, give the contaminated root surface a rinse with solution of pH and osmolarity that provide optimal condition for the cells to live. The solutions suggested by my expensive textbook are cold milk, saline solution (even you contact les solution), saliva or some special solution that is used to store organs during transplant (but that is not practical, ambulance could have one). The above is the ideal management of avulsion. But if for some reason, you cannot replant the tooth, we have to talk about how to store the tooth.

Store it in one of the solutions suggested above, or in between your cheek. Remember, the time counts. Go to the dentist as soon as possible.

All the measures only apply to your permanent tooth, baby tooth that is avulsed shoud never be replanted. As a general guideline, your permanent front teeth erupt at 7-8.5 yo. So, front teeth that you have got before 7 should be baby tooth. The baby tooth may affect the permanent tooth underneath it-PERMANENTLY.

So, let's talk about some stastic now. It is said that tooth replanted in ideal position within 15 minutes in a person with immature tooth (below 13 yo) has a very high chance to live. Otherwise, there can be healing that lead to inflammation, union with the bone and eventual tooth loss. But everything happen after tooth replantation can be taken care of in the dental clinic. Every problem has a solution. If you are interested in knowing more, you can consult your dentist or even ask me. I will be more than happy to tell you.

Last but not least, i will reinforce the same old statement- Prevention is always better than treatment.

If you are driving, wear helmet or put on your seatbelt.
If you are involve in a sport or any activity that can put you at risk of orofacial injury, take some protective precautions. Ask your dentist for a custom made mouthguard and make sure you do utilise them. Remember children are more vulnerable than adult, take care of them too.

There are more knowledge about immediate treatment in trauma. I will talk about it more in the future.
