Do feet really get bigger with age? 脚会一直随着年龄长大？ 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. 这是有可能的：经过多年的磨损，脚部的肌腱和韧带会有损耗。这就会使得脚底变平，那么脚就更宽更长了。但不是每个人都会这样，那些很胖、脚或者踝关节浮肿，又或有过某种病症比如糖尿病的人更容易出现这种情况。一般来说到了70或80岁脚会大一码。 What’s with that stomach-in-your-throat feeling on roller coasters? 做过山车时为什么有胃到喉咙眼的感觉？ 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. |
