Your Feet Can Grow as You Age
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.
Motion Sickness is Caused by Your Insides Actually Shifting
When a roller 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.
Women Handle the Cold Worse than Men
The fairer sex has a higher percentage of body fat and conserves more heat around the core. That helps keep vital organs nice and toasty but not the extremities—and when your hands and feet feel cold, so does the rest of your body. Plus, research suggests that women have a lower threshold for cold than men. When exposed to the same freezing temperature, the blood vessels in women’s fingers constrict more than men’s do, which is why they turn white more quickly.
