It’s certainly possible: After years of wear and tear, tendons and ligaments in your feet may weaken. This can cause arches to flatten, which means feet get wider and longer. It won’t happen to everyone, though—people who are overweight, who get swollen feet or ankles, or who have certain medical conditions, like diabetes, are more prone. If it does happen, the average gain is about one shoe size by age 70 or 80.

這是有可能的：經(jīng)過多年的磨損，腳部的肌腱和韌帶會有損耗。這就會使得腳底變平，那么腳就更寬更長了。但不是每個人都會這樣，那些很胖、腳或者踝關(guān)節(jié)浮腫，又或有過某種病癥比如糖尿病的人更容易出現(xiàn)這種情況。一般來說到了70或80歲腳會大一碼。

What’s with that stomach-in-your-throat feeling on roller coasters?

坐過山車時為什么有胃到喉嚨眼的感覺?

Your insides are actually shifting! When a coaster comes over its crest, slows for a second for added torture, and then plummets downward, the seat belt keeps your rear in place, but some loosely connected internal organs—like your stomach and intestines—get a little “air time.” You’re not damaging your innards by riding even the craziest of coasters (everything returns to its proper place), but your nerves detect the movement, which registers as though your stomach has jumped into your throat.

你的體內(nèi)在翻江倒海!當過山車到了頂端，減速那一秒鐘會加重體內(nèi)的折磨，隨即驟然落下，座位安全帶能保持你的屁股在原位，但卻無法照顧到體內(nèi)的器官，比如胃和腸道就會有點“飄飄蕩”了。其實玩最瘋狂的過山車也不會損壞你的內(nèi)臟(它們最后會回歸的)，但是你的神經(jīng)能感測到運動，就會讓你覺得胃都跑到喉嚨眼來了。
