GOT YOUR EARS ON?

GOOD BUDDY, UH--OH.

HELLO, THERE.

IT IS I YOUR OLD PAL GROVER.

DID YOU KNOW THAT ALL OF US HAVE A HEART?

IT IS TRUE, AND IT IS RIGHT HERE INSIDE OF OUR CHESTS.

MM-HMM.

AND DID YOU KNOW OUR HEARTS BEAT?

WELL, THEY DO!

THEY GO THUMP-THUMP, THUMP-THUMP, THUMP-THUMP.

I LOVE THE SOUND OF A HEARTBEAT.

I HEART HEARTBEATS!

AH HA HA!

WOULD YOU LIKE TO HEAR MY CUTE, LITTLE HEART GO THUMP-THUMP, THUMP-THUMP, THUMP-THUMP?

OH, GOOD.

THEN LET US USE THIS FANCY, LITTLE HEART-LISTENING THINGY, ALSO KNOWN IN SOME PARTS AS A STETHOSCOPE.

NOW LET'S LISTEN.

OOH!

THIS IS COLD!

HA HA HA!

[HEARTBEAT] HEAR THAT?

IS IT NOT BEATING NICE AND SLOW?

AHH.

MY CUTE, LITTLE HEART SOUNDS VERY RELAXED.

- [CLUCKING] - OH!

LOOK!

IT IS A CHICKEN!

LET US LISTEN TO HER CUTE, LITTLE HEARTBEAT.

HERE, CHICKIE, CHICKIE, CHICKIE.

- [CLUCKING] - COME BACK HERE!

- [CLUCKING] - WHY ARE YOU RUNNING, CHICKEN?

- [CLUCKING] I'M RUNNING TO MAKE MY HEART BEAT FASTER!

BAWK BAWK BAWK!

YOU CANNOT CONTROL HOW FAST YOUR HEART BEATS.

MY HEART IS BEATING FASTER.

SEE?

WHEN YOU EXERCISE, YOU NOT ONLY MAKE YOUR MUSCLES STRONGER.

YOU ALSO MAKE YOUR HEART STRONGER.

- UH-OH.

MY HEARTBEAT IS SLOWING DOWN AGAIN.

- WELL, THEN EXERCISE AND GET THAT HEART PUMPING FASTER!

- GOOD IDEA, CHICKEN!

- [CLUCKING] WELL, WHAT ARE YOU WAITING FOR?

COME ON!

MOVE YOUR BODY AND GET THAT HEART BEATING FAST.

- BAAAWK!

[BIRDS TWEETING] - OHH.

GETTING YOUR HEART TO BEAT FAST IS HEALTHY.

FALLING WHILE YOU DO IT, NOT SO MUCH.

- BAWK BAWK BAWK.

OHH.

- OHH.
