American doctors have been trying to figure out the secrets behind Asians being healthier than Americans since the early 90s - The Japan has the lowest mortality rates in the world and Chinese medicine has been around for thousands of years, since around 2000 B.C. only meant that there's more to Asian health philosophy. In Asian medicine, there's an acknowledgment of the whole-body theory of medicine, instead of isolationism that's prevalent in many American doctor's offices.

The main reason behind a better health lies in the difference between Asian and American culture. Diet, exercise, and a holistic approach to medicine all contribute to Asians living longer and healthier than their American counterparts. In addition, the result of the Asian lifestyle has led to a stronger overall immune system and better detoxification(解毒) efficiency.

The more preferred drink in the American lifestyle is soda, beer or coffee. However, in Asian culture, the preferred drink is water or herbal tea. Consumption of water serves to immediately strengthen one's body detoxification program, since water dilutes toxins and helps flush the body. Americans savor red meat and pork, while most Asians prefer chicken, rice and fish. Also, the foods in Asia are mostly organic and lack the hormonal toxins that American food carries. Overall the Asian diet leads to less food-introduced toxins into the body, and allows the body to spend its energy on its immune system rather than toxin control. Also, the fish that Asians consume have very strong immunological effects, providing more antioxidants than the red meat preferred in America.

The average American family has more than one car. In Asia, on average there's 1 car per 4 families. In Asian cultures, people use bicycles more than four-wheeled transportation. The Asian lifestyle also involves more labor and physical work, such as agricultural labor and gardening. The American lifestyle praises white-collar jobs which lead to Americans sitting in front of computer screens for hours on end. Exercise helps detoxification in two ways: it speeds up metabolism, and induces sweat.

Medicine in Asia centers mostly on natural ingredients that have healing properties. Asian medicine also addresses the mind-body connection and the importance of mental balance. There are more traditional medicine doctors per person in Asia than in America. American medicine costs more and is symptom-focused, often ignoring the overall cause of the symptoms. In America, the prescriptions that are chemically derived are dangerous toxins that stress the body's detoxification system. Using Asian medicine means using only natural ingredients, which the body can easily detoxify while getting the same health benefit.

It is not very difficult to adopt the Asian lifestyle and improve your body's detoxification and immune system. You can change your lifestyle today by eating and drinking organic, exercising rigorously at least three times a week, and using organic health alternative therapies over dangerous prescription medicines.

2008年,G淀粉公司雇佣临时人员把仓库改造成第三生产车间。该车间为长80m、宽50m、高15m的桁架砖混结构建筑,分成打包间和产品暂存间。打包间用7m高砖墙与暂存间分隔。打包间内有打包机8台、振动筛8台。振动筛安装在6m高的二层钢制平台上,振动筛内筛子采用木质框架,筛子四角与振动筛用铁质螺栓连接。振动筛开关和电动机为防爆电器设备。
2010年3月10日10时30分,当班班长甲发现4号打包机故障,二层钢制平台滞留了大量淀粉,正散落到打包间地面。甲关停4号打包机,并向车间主任报告。14时,甲带领10名工人到二层钢制平台清理淀粉。一部分工人使用扫把、铁锹等工具清理平台上的淀粉,装包后,通过楼梯把成包淀粉滚落到打包车间地面,或从二层平台直接将淀粉包扔到打包间地面。另一部分工人用铁制扳手卸下筛子,用铁棍敲打清理筛子上的淀粉。
当清理工作进行到15时10分时,突然发生燃爆,而后发生多次爆炸,打包间一片火海,第三生产车间厂房的四面墙体全部倒塌。事发时,打包间和暂存间分别有作业人员19人和79人。事故导致18人死亡、7人重伤、38人轻伤。
事故发生后,当地政府立即成立现场救援指挥部。搜救人员多次进入车间搜救,利用切割机、生命探测仪、液压顶杆、起重气垫等装备进行救援,并在厂房周边同时用消防水枪降温,防止再次燃爆。

根据以上场景,回答下列问题:


分析该起事故的直接原因和间接原因。
