0:00:02 > 0:00:04This is the Let's Go Club, but mini.
0:00:04 > 0:00:06Expect making, exploring,
0:00:06 > 0:00:11super-sizing, dancing, fact-finding and laughing.
0:00:11 > 0:00:14So get ready for more fun from the Let's Go Club.
0:00:19 > 0:00:23Today, we're finding out all about our bodies.
0:00:23 > 0:00:28Boys, girls, old and young.
0:00:28 > 0:00:32Some with a toothy grin and others with gums.
0:00:32 > 0:00:36Freckles, dimples, curly hair.
0:00:36 > 0:00:40We're all very different, but some things we share.
0:00:40 > 0:00:43Let's get to those facts.
0:00:43 > 0:00:47First up, it is impossible to tickle yourself.
0:00:47 > 0:00:49Go on. Try it.
0:00:49 > 0:00:51Are you laughing?
0:00:52 > 0:00:54Are you squealing?
0:00:54 > 0:00:56Nope.
0:00:56 > 0:01:01But when someone else does it to you, well, that is seriously tickly.
0:01:01 > 0:01:04The thing is, your brain knows who's doing the tickling
0:01:04 > 0:01:07and when your brain knows it's you,
0:01:07 > 0:01:10it doesn't let you feel the tickle as strongly.
0:01:10 > 0:01:13So it doesn't really tickle at all.
0:01:13 > 0:01:16Not nearly as much fun.
0:01:16 > 0:01:19So for a proper chuckle, grab a friend.
0:01:19 > 0:01:24Next, most dreams only last a few seconds.
0:01:24 > 0:01:26Ahhh, yawn!
0:01:26 > 0:01:27But the good news
0:01:27 > 0:01:31is that you can have lots and lots of dreams in one night.
0:01:31 > 0:01:35And each one lasts longer than the dream before it.
0:01:35 > 0:01:38Sometimes, your brain joins them all together
0:01:38 > 0:01:42and when you wake up, you feel like you've had one long dream.
0:01:42 > 0:01:46Of course, there are lots of dreams you just don't remember.
0:01:46 > 0:01:50Which is very helpful when it comes to nightmares.
0:01:50 > 0:01:55Next, everyone has their own unique smell.
0:01:55 > 0:01:58Get a whiff of that.
0:01:58 > 0:02:03Your body makes lots of sweat, wee and spit every day.
0:02:03 > 0:02:05And they all have a different pong.
0:02:05 > 0:02:08But when you mix these smells all together,
0:02:08 > 0:02:11you end up with an aroma that's just yours.
0:02:11 > 0:02:14There is an exception to the rule.
0:02:14 > 0:02:17Identical twins smell almost exactly the same.
0:02:17 > 0:02:20And that's not to be sniffed at.
0:02:20 > 0:02:25And finally, your heartbeat changes when you listen to music.
0:02:25 > 0:02:27Sounds good to me.
0:02:27 > 0:02:32Gentle, relaxing tunes can make your heart slow down.
0:02:32 > 0:02:37While exciting, up-tempo music tends to make it beat faster.
0:02:37 > 0:02:40And music that has lots of notes and sounds together
0:02:40 > 0:02:44can even make your heart beat along in time to the tune.
0:02:44 > 0:02:46Fact.
0:02:46 > 0:02:49You can be part of the Let's Go Club, too.
0:02:49 > 0:02:52Grab a grown-up and head to the CBeebies website.
0:02:52 > 0:02:55Remember, we're the club that never closes.
