你以为避孕措施方面有任何新突破大夫就会第一时间告诉你对不对？遗憾的是，大夫很可能对你隐瞒了很多细节，原因何在？或许因为你没有提出任何质疑，她以为 你已掌握了所有需要了解的信息;或许她的日程排得满满，每天接待无数像你这样心切的人，哪有时间与你进行深入交谈，敷衍敷衍了事。
COSMO网站曾经对2000多位女性进行了一项民意调查，有33%的女性回答每年一度的妇科检查大夫只是蜻蜓点水，应付一下而已。恰恰是你不了解的那 些信息可能埋下隐患，伤害到你。在采取避孕措施的女性中，有2/3的女性发现自己“意外”怀孕，原因是采用的方式不正确，或与自己的生活方式配合不当。在 实际操作过程中，避孕方法不可能做到100%的安全，也不可能防止感染性病，但下列7个知之不全的事实却很可能对你的生活产生严重的影响。
秘密1：体重在起作用
介于18-39岁年龄段的女性，如果体重等于或大于58公 斤，口服避孕药有60%可能失败，尤其是雌性激素指标偏低者。体重过高的女性新陈代谢较快，需要更多的荷尔蒙以防止受孕。而且，避孕药有溶脂作用，可能 “呆”在体内贮存脂肪的地方，无法到达应该到的血液中真正发生作用。要是你的体重超过58公斤，最好请大夫推荐其他更为可靠的办法，如宫内避孕器，或避孕 药和避孕套双管齐下，确保万无一失。
秘密2：经久不衰的即最有效的
实际上，有不 少相当有效的避孕方法不为你知晓，从来不曾想像过，也没人向你推荐过。好奇吗？宫内避孕器(IUD)即其中一例。这是置入子宫内的T状小型避孕器，由灵活 的软塑料制成，必须由大夫帮助你嵌入体内。之后，即使卵子已经受精，也不会在子宫里着床成长，只要没什么异常，一两年不管都可以，且不会给性爱添麻烦，非 常方便。
It is really hard to tell which animal is the most poisonous in the world. The one that has the most toxic chemicals? The one that kills the biggest amount of people a year? Or maybe the one with the biggest amount of poison?
First of all, I have to admit that the title is a bit incorrect, because there is a difference between poisonous and venomous animals. A poisonous animal carries harmful chemicals called toxins primarily used for self defense. Therefore venomous animals deliver their toxins by stinging, stabbing, or biting. So poisonous animals are passive killers, while venomous animals are active killers.
Nevertheless, theory aside, they are all really dangerous. So look really closely at each photo, cause next time you meet them can be the last thing you ever see.
1. Box Jellyfish
The top prize for “The World Most Venomous Animal,” would go to the Box Jellyfish. It has caused at least 5,567 recorded deaths since 1954. Their venom is among the most deadly in the world. It’s toxins attack the heart, nervous system, and skin cells. And the worst part of it is that jelly box venom is so overpoweringly painful, that human victims go in shock, drown or die of heart failure before even reaching shore. Survivors experience pain weeks after the contact with box jellies.
You have virtually no chance to survive the venomous sting, unless treated immediately. After a sting, vinegar should be applied for a minimum of 30 seconds. Vinegar has acetic acid, which disables the box jelly’s nematocysts that have not yet discharged into the bloodstream (though it will not alleviate the pain). Wearing panty hose while swimming is also a good prevention measure since it can prevent jellies from being able to harm your legs.
Jelly box can be found in the waters around Asia and Australia.
2. King Cobra
The King Cobra (Ophiophagus hannah) is the world’s longest venomous snake – growing up to 5.6 m (18.5 ft) in length. Ophiophagus, literally means “snake-eater” as it eats other snakes. One single bite of this deadly snake can easily kill a human. This snake is even capable of killing a full-grown Asian Elephant within 3 hours if the larger animal is bitten in a vulnerable area such as the trunk.
It’s venom is not as toxic as other venomous snakes, but King Cobra is capable of injecting 5 times more venom than black mamba and can result in mortality up to 5 times faster than that of the black mamba. It is quite widespread, ranging across South and South-east Asia, living in dense highland forests.
