  Welcome to Kick Ass Daily, where we bring news, trivia, fun
• 0:04
  facts, and more just for curious kids like you.
• 0:07
  Get ready, because today we're going on an adventure into a
• 0:10
  world that's all around us, but so tiny you can't even see it
• 0:14
  with your eyes. We're talking about bacteria.
• 0:17
  That's right, those super small living things that are
• 0:20
  everywhere in the air, on your skin and your food, and even
• 0:23
  inside your tummy. But here's the big question.
• 0:27
  Are bacteria good or bad? Well, let's find out together as
• 0:30
  we explore the amazing battle of good versus bad bacteria.
• 0:34
  First, let's start with the basics.
• 0:36
  What are bacteria, anyway? Imagine you have a super
• 0:40
  powerful magnifying glass that can zoom in a million times.
• 0:43
  If you looked at a drop of water through it, you'd see little
• 0:46
  wiggly dots moving around. Those are bacteria.
• 0:50
  They're so tiny that millions of them could fit on the tip of
• 0:53
  your pencil. Bacteria are a type of germ, but
• 0:56
  not all bacteria are bad. In fact, most bacteria don't
• 1:00
  harm us at all, and some are actually our friends.
• 1:03
  Now let's picture your body as a huge, busy city.
• 1:06
  Every city needs workers to keep things running smoothly in your
• 1:09
  body. City good bacteria are like the
• 1:12
  helpful workers. They keep everything clean,
• 1:15
  organized, and safe. These good bacteria are called
• 1:18
  probiotics, and you might have heard of them if you've ever
• 1:21
  eaten yogurt or seen a commercial for healthy snacks.
• 1:24
  Probiotics live mostly in your gut, which is another word for
• 1:28
  your stomach and intestines. So what do these good bacteria
• 1:31
  do? Imagine they're tiny superheroes
• 1:34
  wearing capes and zooming around your tummy.
• 1:36
  Their mission? To help you digest your food,
• 1:39
  breakdown things your body can't do on its own, and even protect
• 1:43
  you from invaders, like bad bacteria.
• 1:45
  Some good bacteria make vitamins that your body needs, like
• 1:48
  vitamin K and certain B vitamins.
• 1:50
  Others help your immune system, which is like your body's police
• 1:53
  force. Stay strong and ready to fight
• 1:56
  off germs. Did you know that there are more
• 1:58
  bacteria living inside your body than there are people on Earth?
• 2:02
  That's right, Scientists say there can be as many as 100
• 2:05
  trillion bacteria living in and on your body.
• 2:08
  That's a one with 14 zeros. Most of them are good, and they
• 2:12
  work together to keep you healthy.
• 2:14
  But just like every city has its share of troublemakers, your
• 2:18
  body has to deal with some bad bacteria too.
• 2:20
  These are the bacteria that can make you sick.
• 2:23
  Bad bacteria are like the mischief makers of the bacteria
• 2:26
  world. They sneak in, cause trouble,
• 2:29
  and sometimes make your body feel yucky.
• 2:31
  They can cause things like sore throats, ear infections, and
• 2:34
  tummy aches. When bad bacteria get into your
• 2:37
  body, your immune system jumps into action to stop them.
• 2:41
  Let's imagine a scene in your body city.
• 2:43
  The good bacteria are busy cleaning up, helping digest
• 2:46
  food, and making vitamins. Suddenly, a group of bad
• 2:50
  bacteria tries to sneak in through your mouth when you eat
• 2:53
  something that wasn't washed properly.
• 2:55
  The good bacteria sound the alarm to your immune system and
• 2:59
  together they work to chase away the bad bacteria.
• 3:02
  Sometimes your body wins the battle quickly and you don't
• 3:06
  even notice. Other times you might get a
• 3:08
  fever or feel tired while your immune system fights the germs.
• 3:12
  Here's a fun fact, not all bad bacteria are bad all the time.
• 3:16
  Some bacteria that can make you sick only do so if they get in
• 3:19
  the wrong place or if your immune system is weak.
• 3:23
  For example, there's a bacteria called E coli.
• 3:26
  Some types of E coli are harmless and live in your gut,
• 3:30
  helping you digest food. But other types can make you
• 3:32
  sick if you eat undercooked food.
• 3:35
  So it's all about balance and keeping bacteria where they
• 3:38
  belong. You might be wondering, how do
• 3:41
  good bacteria help protect us from the bad ones?
• 3:43
  Picture a playground with limited swings.
• 3:46
  If all the swings are taken by good kids who play nicely,
• 3:50
  there's no room for the troublemakers to cause problems.
• 3:53
  Good bacteria crowd out the bad ones, making it harder for them
• 3:56
  to find a place to live and multiply.
• 3:59
  When you have lots of good bacteria, they help keep the bad
• 4:02
  bacteria in check. So how can we help the good
• 4:05
  bacteria in our bodies? One way is by eating foods that
• 4:08
  they love. Foods like yogurt, kefir, and
• 4:12
  sauerkraut are full of good bacteria or probiotics.
• 4:16
  Fruits, vegetables, and whole grains are packed with fiber,
• 4:19
  which is like a favorite food for your good bacteria.
• 4:22
  When they eat the fiber, they grow strong and healthy, ready
• 4:26
  to protect you. Did you know that even your pets
• 4:29
  have bacteria living in their tummies?
• 4:31
  All animals, from tiny ants to giant elephants, have their own
• 4:35
  little communities of bacteria helping them out.
• 4:38
  It's like every living creature has its own team of helpers.
• 4:42
  Now let's talk about how we can avoid giving the bad bacteria a
• 4:45
  chance to make a sick. Washing your hands before you
• 4:48
  eat, after you play outside, or after you use the bathroom is
• 4:51
  one of the best ways to stop bad bacteria.
• 4:54
  Soap and water wash away those sneaky germs before they can get
• 4:57
  into your body. Also, make sure to eat food
• 5:00
  that's been cooked properly and washed well.
• 5:03
  That's another way to keep the bad bacteria away.
• 5:06
  Sometimes when people get sick from bad bacteria, doctors might
• 5:10
  give a medicine called antibiotics.
• 5:12
  Antibiotics are like special tools that target and destroy
• 5:15
  the bad bacteria. But here's something super
• 5:18
  important. Antibiotics don't know the
• 5:20
  difference between good and bad bacteria.
• 5:23
  They can wipe out both. That's why it's important to
• 5:26
  only take antibiotics when a doctor says you really need
• 5:29
  them. If you take them when you don't
• 5:31
  need to, you might hurt your team of good bacteria and make
• 5:34
  it harder for your body to stay healthy.
• 5:37
  Here's another Did You Know moment?
• 5:39
  Bacteria aren't just in our bodies.
• 5:41
  They're everywhere. On your desk, in the soil, in
• 5:44
  the ocean, and even floating through the air.
• 5:47
  Some bacteria help plants grow by turning things in the soil
• 5:50
  into food for roots. Others help clean up oil spills
• 5:54
  in the ocean by eating up the oil.
• 5:56
  Some bacteria are even used to make cheese and Pickles.
• 5:59
  Without bacteria, we wouldn't have some of our favorite foods.
• 6:03
  Let's take a quick quiz. True or false?
• 6:06
  All bacteria are bad. If you said false, you're
• 6:09
  absolutely right. Most bacteria are either good or
• 6:12
  harmless. Only a tiny number actually make
• 6:15
  us sick. Bacteria are some of the oldest
• 6:18
  living things on Earth, and they've been around for billions
• 6:20
  of years, way longer than dinosaurs.
• 6:23
  So what have we learned today? Let's recap.
• 6:27
  Bacteria are tiny living things that are all around us and even
• 6:30
  inside us. Good bacteria like probiotics
• 6:34
  help our bodies digest food, make vitamins, and protect us
• 6:38
  from bad bacteria. Bad bacteria can make us sick,
• 6:42
  but our immune system and good bacteria work together to keep
• 6:45
  them in check. We can help our good bacteria by
• 6:48
  eating healthy foods, washing our hands, and listening to our
• 6:51
  doctors about medicine. And remember, bacteria aren't
• 6:55
  just in our bodies. They help plants grow, clean up
• 6:58
  the environment, and even make some of our favorite snacks.
• 7:01
  The next time you eat yogurt or see a commercial about
• 7:04
  probiotics, you'll know you're feeding your team of tiny
• 7:07
  superheroes. And when you wash your hands or
• 7:10
  eat your veggies, you're helping your good bacteria stay strong.
• 7:14
  Bacteria may be invisible to our eyes, but they play a huge role
• 7:18
  in keeping our world and our bodies healthy.
