You can be just as brisk, just as active, just as light-hearted now as you were ten or twenty years ago.

现在的你完全能够和十年、二十年前的你一样那么活泼、一样那么积极、一样那么的无忧无虑。

Doing something more active can certainly help, and if you're a dedicated gym user, that may be how, but so can a brisk walk in the countryside.

做些包含更多活力的事情应该会有所帮助，而如果你是健身房的常客那当然更好，否则在乡村小道上来段快走也不错。
