Can we do something about it? Well science is saying yeah, maybe.

我們可以做些什麼呢？科學說也許可以。

Some fascinating experiments done with mice...as we get older our cells age and some of them

一些有趣的老鼠實驗 ... 隨著年齡增長，我們的細胞也老化了，

become what are known as senescent cells. They no longer divide but they do

其中一些會變成衰老細胞，

release compounds that are inflammatory and that can damage tissues.

它們不再分裂，但會釋放具發炎性且損害組織的化合物。

Well, in a very interesting experiment scientists injected young mice with senescent cells

在一個有趣的實驗中，科學家給幼鼠注射衰老細胞，然後它們變老了。

and they got old. They became slower, they reacted more slowly

它們會行動緩慢、對所有事情都反應遲鈍，

to everything and then they injected them with drugs, one of them derived from

然後科學家又注射藥在牠們身上，成份裡其中一種是從蘋果皮上萃取的，

apple peels, the other one a pharmaceutical substance, and it turned out that after

另一種是藥物，事實證明，

injecting it those mice regained their youthful appearance.

當注射後，這些老鼠恢復了年輕樣貌。

Now granted this is only with mice and as we say mice are not men or women,

現在只允許老鼠這麼做，就如同我們說的，老鼠不是男人或女人。

Is there anything that we can do that is more applicable to us?

有什麼更適合我們做的嗎？

Well, maybe there is. It's a calorie-restricted diet.

也許有，就是熱量控制的飲食。

Science has shown over and over again from rodents to dogs to monkeys

科學從嚙齒動物到狗、然後猴子都一再證明，

that if they are put on a calorie restricted diet they age more slowly.

如果牠們都有都有做到熱量控制的飲食，牠們就會減緩衰老。

What does that mean, a calorie restricted diet?

那是什麼意思，熱量控制的飲食？

Well, may not be very appealing because it means eating less than the 2,000 calories

因為這表示我們一天正常只能吃少於 2,000 大卡，這也許不太吸引人。

we normally a day. Of course, it doesn't mean that you just eat fewer potato chips or hot dogs.

當然這並不是要你只吃少量的洋芋片或熱狗。

It has to be a balanced diet and it's possible to do that.

而是均衡飲食，這是可能做到的。

Now I wish that we had long-term experiments with humans. We don't have that.

現在我希望我們可以對人類做這個長期的實驗，雖然現在還沒有。

But it is an interesting possibility that just cutting down on food is going to increase our longevity.

但減少食物攝取量會增加我們的壽命，這是很有趣的可能。

It's not a good idea to be hungry all the time and if it's gonna make you live

一直保持飢餓狀態不是好主意，而且這會出現一個問題，

longer question comes up is it worthwhile living longer if you're going

如果你將會錯過人生中美好的事物，

to miss some of the good things in life?

這是否值得讓你延長壽命？

We're going to take a scientific look at that this week.

我們將在本週進行科學考察。

Our annual Trottier Public Science Symposium is entitled Longing for Longevity

我們一年一度的 Trottier 公共科學研討會主題是渴望長壽，

and we have some great speakers: Dr. David Sinclair from Harvard

然後我們有很棒的演講者：來自哈佛大學的 David Sinclair 博士，

is going to address whether or not there are any supplements we can take to reduce

他將會告訴我們是否可以透過任何補充劑來減緩老化過程。

the aging process. Kelly Dobos will look at cosmetics, what can we put on our

Kelly Dobos 將著眼於化妝品，我們可以擦什麼在皮膚上預防老化？

skin to perhaps retard aging? And we will also have the legendary Dr. Ruth discuss

我們還邀請到傳奇的 Ruth 博士，他將會探討五十歲之後是否還有性？

whether or not there is sex after 50. You are all invited. It takes place on Tuesday

所有人都歡迎參加，此研討會在星期二和星期三的七點開始，

and Wednesday at 7 o'clock at the Centre Mont Royal, corner of Sherbrooke and Mansfield.

地點在皇家山中心，是在舍布魯克和曼斯菲爾德的轉角處。

It's absolutely free. Everyone is invited. We're gonna have a great time.

這是完全免費的，每個人都可以參加，我們一定會度過愉快的時光。

And in the meantime I will try to cut back on the calories in my diet.

同時，我將試著減少飲食中的熱量。
