I'm not sure we can, to be honest. As we get older, we slow down, we lose muscle and things we used to do become harder and more strenuous. This means that older people just don't have the strength to do certain things, or if they do them, they get tired pretty quickly. Obviously, not being overweight and being active are key to keeping going as long as possible but it's part of the natural process of life as we age. It would be great if there were a cure or something we could take to give us more energy but, unfortunately, it doesn't exist.
老實說,我們可能做不到。隨著年齡增長,我們開始放慢步伐,失去肌肉,我們過去容易做的事情變得更加困難和費力。這意味著老年人就是沒有足夠的力氣做某些事情,或者即使做了,也會很快感到疲倦。顯然,保持正常體重和積極行動對於盡可能保持活力至關重要,但隨著年齡增長,這是生命的自然過程之一。如果有一種治療方法或者可以讓我們獲得更多能量的東西就太好了,但很遺憾,這並不存在。
