阅读下面一段课文，然后回答问题：
“人生不满百”，大致是不错的。当然，老而不死的人，不是没有，不过期颐以上不是一般人所敢想望的。数十寒暑当中，睡眠去了很大一部分。苏东坡所谓“睡眠去其半”，稍嫌有点夸张，大约三分之一左右总是有的。童蒙一段时期，说它是天真未凿也好，说它是昏昧无知也好，反正是浑浑噩噩，不知不觉；及至寿登耄耋，老悖聋瞑，甚至“佳丽当前，未能缱绻”，比死人多一口气，也没有多少生趣可言。掐头去尾，人生所余无几。就是这短暂的一生，时间亦不见得能由我们自己支配。约翰逊博士所抱怨的那些不速之客，动辄登门拜访，不管你正在怎样忙碌，他觉得宾至如归，这种情形固然令人啼笑皆非，我觉得究竟不能算是怎样严重的“时间之贼”。他只是在我们的有限的资本上抽取一点捐税而已。我们的时间之大宗的消耗，怕还是要由我们自己负责。

What is the main reason for reducing salt in food?
My boyfriend really enjoyed canoeing (划独木舟), and it took me a while to finally persuade himto take me on a canoe trip. Despite his great skill, he was nervous about my safety and described manyterrible situations that could happen. "They could also not happen," I said. I wanted to prove that I wastough and capable of adventuring.?
This would be a romantic adventure. We would row the canoe on the lake under a beautiful bluesky. I was confident it would all go according to plan.?
It did not go as planned. Instead,?it all went downhill. We hit a headwind (逆风). The flies werethe worst. An unknown animal outside our tent in the night forced us to get up twice to scare it away.We walked through knee-deep mud; we moved around so many fallen trees that we lost the wayfrequently. We had an unexpected thunderstorm on our second night. We hid in our tent from the bugs(虫子), too tired and bitten to even hold each other. When we were finally back in the car, my skinwas hot and angry with bug bites, I had barely slept in 72 hours and I had an injury on my forehead fromhitting it on the canoe.?
Yet I realized that I wanted to do it all again. Because I swam in a lake so warm it felt like asummer pool. ?I ate lunch on an island with the most beautiful pine trees. ?I' d also never beforeappreciated how thunder can make the ground tremble. I know why my boyfriend loves canoeing somuch. It' s for the challenge, the space, and the beauty of moving forward with your own two hands ina place of natural wonder. He didn' t say "I love you. " He said I was a good partner. I' ve foundsomething that I really like to do. That' s the more important thing.?
