What Causes Hiccups? And More Tricky Kid Questions
Do Fish Sleep?
Sort of. It’s hard to catch some shut-eye when you can’t shut your eyes. But according to the experts at the Mystic Aquarium,
in Mystic, Connecticut, most fish do enter a resting period during which their metabolism slows. Some just drift aimlessly,
while others nestle in coral or sand so they won’t be disturbed. Even as they snooze, however, fish remain alert to potential
danger, and the smallest ripple will rouse them instantly—no alarm clock necessary.
Why Do Feet Smell?
They’re covered in tons of bacteria—and when bacteria excrete waste (or, in kid terms, poop), it really stinks, says Jane Andersen, M.D., a podiatrist in Chapel Hill, North Carolina. Why the feet in particular? Bacteria thrive in wet places, and our tootsies (which have a startling 250,000 sweat glands apiece) are among the body’s dampest spots.
