笑其實是演化上將人與人連結為一個群體的工具，靈長類也是如此。有些研究笑的科學家甚至認為，笑的主要功能就是增進人與人之間的互動，而笑對健康的好處主要來自它所提供的人際互助。

促進血液循環-- 笑使血流量平均增加20%。 血液循環的速度增加回減少血液在血管壁上附有的可能性。

米勒（Michael Miller）醫師說：「笑對於心血管的益處與有氧運相當，而且又不會有運動後肌肉疲勞與痠痛的缺點。」

人在開懷大笑的時候自身的血流量會增加，從而促進血液循環這樣加強人體的新陳代謝

止痛-- 當你笑時,大腦的神經細胞就會釋放出一種叫B-內啡肽物質,它是大腦中專門負責傳遞讓人產生快感和止痛信息的激素,嗎啡的止痛效果很好就是因為含有相同的物質。

笑一笑的好處還是很多的，它可以起到減壓的作用，因為它可以使大腦的中樞神經一直處於興奮的狀態，從而緩解負面情緒

降壓-- 大笑時,體內產生的B-內啡肽還有助於修復血管。 另外一個可能的原因是,大笑促進一氧化氮釋放，這種氣體可以使內皮等部分血管壁放鬆。 所以大笑時血壓會回降。

增加免疫能力-- 一項對血液的研究顯示 ,在觀看幽默錄像的前後分別測試血液,結果發現看後的免疫系統特別活躍,血液中抗體含量和白細胞的數量都較原來明顯增多。 並且體內的抗體循環也加快,這些都能增強免疫能力,對抗病菌。 而且,開心一下還會增加唾液中的抗體,讓身體的第一到防線更穩固。

當捧腹大笑時，腹腔壓力急遽變化，可以加速淋巴的循環 10～15 倍，一方面加速排毒，另一方面也幫助將免疫細胞部署至身體各部位。笑應該是提升免疫力既輕鬆又愉快的一種方式了。

促進肺功能-- 大笑令呼吸系統更順暢.我們笑的時候,鼻孔和口也張開,肺部擴張,肺活量增加,使吸入氧氣增多,大量二氧化碳被呼出。 不但可以促進肺功能,還可以清潔呼吸道。 而且大笑後的血液中氧氣含量也大大增加。

促進消化-- 大笑時肩膀會聳動,胸膛搖擺,橫膈膜震蕩,膈肌上下運動量亦會因此而增大,使內臟得到按摩,所以對消化系統大有裨益。 而且大笑還可以促使更多血液流入腸胃,改善消化功能。

放鬆肌肉-- 人在肌肉緊張的時候,牙齒是咬緊的.而當下頜處於下移狀態時,也可以反射性地帶動全身的放鬆。 大小時可以牽動臉部,手臂,頸部,胸部等肌肉發生運動,停止發笑後,這些肌肉便很快放鬆下來。

減肥-- 大笑時身體會有80組肌肉抽動,大笑1分鐘等於做運動45分鐘。 研究人員計算出人體在大笑狀態下比嚴肅狀態下多消耗了20%的熱量,所以如果每天開心微笑10--15分鐘,可以消耗50千卡的熱量。 這意味著每年就可以減肥2KG。 並且,大笑可以促進平時很少運動的腹部肌肉。

因為人在小的時候身體大部分的肌肉會抽動，笑一分鐘相當於運動半小時以上，如果每天開心10分鐘左右，則瘦身真的是一件非常輕鬆的事情。

美容-- 大笑可使皮質醇減少,而皮質醇往往是面部豆豆的罪魁禍首之一。 大笑的時候,血液循環增加,也可以使得更多的養分被運送到本世紀末皮膚,運走皮膚下沉積的壞物質,從而改善皮膚的營養狀況。

笑一笑使肌膚變好的同時對人體的健康也是有較多的益處的。止痛，人在笑的時候，大腦的神經細胞會釋放出一種物質——B-內啡肽物質

減少偏頭痛的發生-- 偏頭疼大多是因為神經長期過於緊張,減少偏頭痛發生幾率的方法就是精神放鬆和增加大腦的氧氣供應。 大笑的時候大腦處於一片空白,使人從緊張狀態中放鬆。 而且大笑還可以加速血液循環並使得循環中的氧氣增加,給大腦提供更多的氧氣。

笑聲的感染力-- 神經認知研究所的蘇菲史考特（Sophie Scott）教授的研究顯示，當聽到笑聲時，腦部負責笑的區域會變得較活躍，也準備以笑為回應。

开怀大笑带来的性爱好处 笑声是一剂天然的“催情药”，爱笑的人性生活次数更多。

美国两性心理学家蒂芬妮达维斯博士指出，目前已有多项研究表明，欢笑可以使大脑 产生更多的内啡肽快乐激素，这种激素可以让人变得更积极、更外向、更合群，因此更容易吸引异性。

经常大笑还能刺激脑垂体腺，产生更多内啡肽，减少压力，进 而提高性欲，让人可以很快进入激情状态。

相爱的两个人在发生亲密行为前，愉悦的微笑或开怀大笑，都能带来积极情绪，引发共鸣，唤起双方性兴奋。

科学家通过研究发现，经常大笑不仅能改善心情，还会有防治疾病的作用。

笑聲是可以傳染的。研究人員已經證實，笑聲會「胳肢」聽者大腦的同一個區域——微笑的時候那個區域處於活躍狀態。聽者大腦的反應會幫助面部肌肉展現發自內心的笑容。

人們聽到愉快的聲音時基本上是無法控制微笑或者大笑的衝動的。

愉快的聲音可以幫助人們在社交中建立相互影響，營造彼此之間牢固的關係。

在不同產業的七十個團隊中，人們一起開會的兩個小時之內，便會產生共同的情緒，不管好或壞。

我們腦中的開放迴路有一部分的設計會偵測微笑和笑聲，使我們產生相同的反應。科學家的理論是，這種動力在遠古以前就已裝設於人類的大腦，因為微笑和大笑是鞏固盟友的方式，藉此幫助種族得以生存。

領導者擔負起管理自我及他人情緒這項基本任務的意涵是：幽默能促進擴散有活力的工作氣氛，但就像一般領導者的情緒一樣，幽默必須與組織的文化和現實相呼應。

只有真實的微笑和大笑才會傳染。從高層開始的情緒傳染的最快，因為每個人都看著老闆，會從他那兒接收情緒的訊號。即使不是很常看得到老闆，例如在樓上關起門來辦公的執行長，但老闆的態度影響他直接下屬的心情，會像骨牌效應一樣擴散至全公司。

I was taught that to create anything you had to believe in failure, simply because you had to be prepared to go through an idea without any fear. Failure, you learned, as I did in art school, to be a wonderful thing. It allowed you to get up in the morning and take the pillow off your head.

I liked working on 'The Grudge 2.' It was really fun, and I got to meet a lot of cool people. I think the film is a fine example of horror, and I felt excited that I could act in something like that.

I need to have small morsels of sweets. If I have a day with the fam with a big family dinner, then I'll indulge... but then the next day or two I'll really be strict. I learned that from Dolly Parton, by the way!

I perceive and relate to the world through where I grew up; that's part of me. It's what I judge everything else against.

Coffee the finest organic suspension ever devised.

I certainly saw science as a kind of calling, and one with as much legitimacy as a religious calling.

I normally don't eat junk food.

We thought we were going to go up against SNL on Saturday Nights - that would have changed things so much that it's almost impossible to speculate what might have happened.

I don't think shoving my butt into people's faces will tell them anything about who I am. How is that connecting to your audience? What is that doing for your music?

I am a leaf on the wind. Watch how I soar

Good things happen to those who hustle.

I want to make sure that I fulfill the promises that I made to New Mexicans. That's extremely important to me.

I find in my poetry and prose the rhythms and imagery of the best - I mean, when I'm at my best - of the good Southern black preachers. The lyricism of the spirituals and the directness of gospel songs and the mystery of blues are in my music or in my poetry and prose, or I missed everything.

Most players ... do not like losing, and consider defeat as something shameful. This is a wrong attitude. Those who wish to perfect themselves must regard their losses as lessons and learn from them what sorts of things to avoid in the future.

I grew up in the suburbs and was raised on rap radio, so it took me a long time to stumble upon the acoustic guitar as a resource for anything.

I realised those things my ego needed - fame and success - were going to make me terribly unhappy. So I wrenched myself away from that. I had to. I had to walk away from America and say goodbye to the biggest part of my career because I knew, otherwise, my demons would get the better of me.

People tell me that my appearance in real life is better than on-screen. Perhaps people think I am exactly like the characters I play on TV.

It is impossible to begin to learn that which one thinks one already knows.

People even more than things have to be restored renewed revived reclaimed and redeemed never throw out anyone.
