How do they do it in Japan, France and other countries? Can you slim down by kissing too much? Below are some of the most curious things about kissing.

    2. Lovers swap saliva containing various substances e.g. fats, mineral salts, proteins while kissing. According to latest studies, the exchange of the above substances can give a boost to the production of antibodies which are made specifically to deal with the antigens associated with different diseases as they are encountered.

    3. As a rule, 66 percent of people keep their eyes closed while kissing. The rest take pleasure in watching the emotions run the gamut on the faces of their partners.

    誰都知道怎么接吻。問題是：你知不知道關于接吻還有很多有趣的事情和細節？接吻對你是好還是不好？在日本、法國和其他國家，人們是怎么接吻的？經常接吻能減肥么？下面這些就是一些有關與接吻很有趣的事情。

    1、接吻過程過程中要動用29塊面部肌肉。換句話說，接吻是一種有效地預防皺紋的運動。

    2、情人接吻時交換的唾液含有多種成分，比如脂肪、礦物質、蛋白質等。根據最新的研究，這些物質的交換可以增強抗體的產生，這些抗體是在面對能疾病的不同抗原所特別產生的。

    3、作為一種潛規則，66%的人在接吻時會閉上眼睛。另外一些人則喜歡觀察他們的伴侶在接吻時臉上的表情變化。

    4、根據美國的統計數字，美國女性在結婚之前平均會親吻80個男人。

    5、一個飛快的輕吻可以消耗2-3卡路里，而法式熱吻則會消耗至少5卡路里的熱量。

    6、嘴唇的敏感度是手指的200倍。

    7、那些在出門前跟妻子吻別的男人比那些直接關上門離開的男人要長壽5歲。后面那種男人更容易發生車禍。

    8、90秒鐘熱吻會升高血壓、加速脈搏。還會增加血液中的荷爾蒙，會導致生命縮短一分鐘。

    9、法式熱吻在法語里被稱作"靈魂時刻".不只嘴唇在工作，舌頭也不可缺少。而熱情的法國人還發明了這種靈魂之吻的變種，只有舌頭起作用。

    10、和常見的觀點相反，愛斯基摩人不僅僅用彼此蹭鼻子來表達愛意。鼻子碰到一起的時候，嘴唇也會微微張開。然后愛斯基摩人會深深呼吸，把這口氣閉著嘴傳出去。在感受到彼此的氣息之后，他們還會用鼻子摩擦彼此的臉頰一段時候。

    11、在日本、臺灣、中國和韓國，在公開場合接吻往往讓人皺眉頭。典型的日本式接吻看起來就像是在譴責西方人過度開放的道德尺度。即使是最好的情況，看起來也像是純潔的一啄，就像70年代早期的蘇聯青少年在第一次約會的時候會做的那樣。在通常情況下，兩個日本人在轉過頭輕輕一啄之前都需要應該保持一定的距離。（譯者：呵呵，現在應該不這樣了吧。至少中國不是了）

    12、接吻會產生一種物質，麻醉的效果是嗎啡要強200倍。這也就是為什么在接吻的時候，人會有種輕飄飄的幸福感。

    13、接吻能幫助女性放松，并緩解壓力造成的不適。

    14、平均來說，人一生中花在接吻上的時間是20160分鐘，大約是兩周。
