这很有趣。我遇到了一个曾经做过很多登山的人。我问他哪个更难，上升或下降？他毫无疑问地说，因为您非常专注于到达顶部，所以您避免了错误。
(It's funny. I met a man once who did a lot of mountain climbing. I asked him which was harder, ascending or descending? He said without a doubt descending, because ascending you were so focused on reaching the top, you avoided mistakes.)
