- Grandmas like to give a lot of health advice,
some of it true, some of it eh...
I'm about to fact check them.
But for this video, I got the coolest grandma in the game.
- Hey, I'm GB, the best grandma in the game!
(ding)
Pee-whoop!
Well, hey, don't swallow your gum.
It gonna stick in your stomach for the next seven years.
- Imagine you swallow a piece of gum
and it stays there for seven years.
What happens if you swallow five pieces of gum?
I actually covered this on a "Responding to Comments" video.
I must know, where did this urban legend start from?
No, you cannot digest the gum.
So it will go right through you and come out the other side.
And why seven years? Does the gum thing go, like,
"Oh, year five. Still got to chill.
Year eight. Oh no, we're late."
You like that rhyme. I know you liked it. Don't, don't lie!
- Okay. It takes more muscles to frown
than it does to smile.
- Aww. I think that's true.
Let's do a quick search just to confirm.
All right. Frowning, 11 muscles total.
Smiling, 12 total. Wait.
No.
Is this true?
Different people smile differently
and use different muscles. So there is no answer to this.
Okay. I'm with it, Gram and I both believe it.
So for us, it's true.

- The best thing to eat when you're sick
is chicken noodle soup. It helps a lot
because I know that for a fact.
- Not only do I agree as a medical expert,
I agree because the scientific research agrees.
We've tested this. It's warm, it has electrolytes,
little salt, little bit of calories.
Can you believe that?
The chicken noodle soup thing has
actually medically been proven to help with the common cold?
I mean the symptoms of the common cold. Good job, grandma.
- Now, if you've got a cold stay in bed,
and don't exercise, and relax.
- I like that. I like that advice.
I will go a little one step further, Grandma.
I'm sorry. Don't get mad at me.
If you have a very, very mild upper respiratory illness,
you can do some mild exercise. I mean,
rest and hydrate is good advice,
whenever you have a viral illness.
So I'm not against what Grandma's selling here.
She's spitting' facts.
She's spitting' hard facts.
- [Matthew] Why would that work?
- I don't know. But it does. Trust me.
- I trust you. Ooh, you flirting' with me?
- Cracking your knuckles will give you arthritis,
but I don't think so.
- Grandma Mythbuster in the house!
(Dr. Mike cracks his knuckles)
- ASMR challenge.
But really cracking your knuckles
is just about nitrogen bubbles popping
within the joint. And guess what?
After a few minutes of cracking your knuckles,
those nitrogen bubbles reform,
and we've seen it on X-rays.
Actually, check it out right here.
- To get rid of a bruise more quickly,
cover it with raw meat. And I have heard that,
but I'm not sure about it.
- I wouldn't recommend putting raw meat
so you can get bacteria exposure onto your skin.
- (groaning)
- No, you got a bruise?
Put some ice on it, or, you know what?
Let it be a bruise. Own it. Love it. Hug your bruises.
- An apple a day'll keep the doctor away? Maybe.
- (Dr. Mike laughs)
- She said, maybe.
Unless you throw it at me, like that meme.
Unless you didn't pay your co-pay.
Then they'll still chase you.
Be careful with these doctors out here.
No, apple is great. It has fiber.
It has vitamins, nutrients, phytonutrients,
good stuff, but it will not stop you from ever getting sick.
I mean, I got, I think that goes without saying.
They're yummy too. Like, that's the problem.
Like, we've chemically engineered all these foods now.
You give a kid an apple and they're like,
"Ugh, that's not sweet."
It is sweet. Just, your freaking Jolly Ranchers,
like chemically designed to be like
a hundred times more sweet than the right, real apple.
Nothing against Jolly Ranchers. I love 'em. Green apple?
- If you pluck a gray hair, two will grow in its place,
and you could look at my head,
and you know that's the truth.
- Why, has she been picking, or plucking her hairs?
I have gray hairs. I don't know if you can see here.
I plucked them sometimes. And you know, what's weird?
Sometimes when I plucked them, and they're really long,
I put them against my mirror and they just stay there.
(spooky music)
I don't know why. I think it's like,
the root kind of, like, is sticky still,
and it attaches to my mirror, and it just stays there.
I'm so weird.
It's usually the old one. Like a long one.
Like a really long one. I'm like, ooh.
I want to remember this gray hair.
- If you eat a black watermelon seed,
a watermelon will grow in your stomach.
And I think that's a lot of wrong.
I don't think that would happen.
- Grandma fact-checking grandma myths!
Re-titling the video right now.
Imagine if you ate seeds that you just end up
growing watermelons out of it.
- If you cross your eyes for longer than seven seconds,
it'll stay that way. But that's an old saying.
And I, I'm not sure about that.
- No, it's not true.
You have muscles around your eyes that are perfectly capable
of moving your eyes sideways, up and down, horizontally,
diagonally. And they return back to normal.
That's what muscles do. That's like saying,
imagine you flex and your arm will stay like that forever.
It won't.
- [Male Voice] Three, four, five,
Six, seven!
- Am I good?
- [Male Voice] 7, 7, yeah.
- I'm good, right?
- [Male Voice] You can uncross your eyes.
- I did.
- [Male Voice] You can uncross.
- Eyes are uncrossed.
- [Male Voice] No, they're still crossed.
- No.
- [Male Voice] Mike, you already got seven.
- No, no, no. I'm good. I'm good!
- No sugar before bed.
It'll make you hyper because sugar gives you energy and
all kinds of good hyper stuff.
- Grandma, I know that's what you told your grandchildren,
but that ain't true. That ain't true, Grandma!
Sugar actually makes an insulin spike and probably
makes you sleepy and crash,
more than it does give you energy.
That whole kids get hyper after sugar thing
is really not true.
Maybe that happened in the beginning when people were
getting Coca-Cola and that had sugar and caffeine in it,
we're giving caffeine to kids!
And then they get hyper and we're like, "Ssh, no!"
- [Matthew] Why would it make you hyper?
- Sugar gives you energy and peps you up,
and sugar's good. Good.
(Grandma laughs)
- I think Grandma just likes sugar!
Grandma needs a little sugar in her life.
Remember the brain does work on glucose,
so she's not wrong on that part.
- Okay. Now don't sit too close to the TV,
or it will hurt your eyes.
- Grandma, this is so true! We sit all the time,
looking at computers, looking at books,
and in order for your eye to focus on something that's
really close to your eye,
it actually has to constrict and focus.
Over time that actually causes harm,
where your farsighted vision goes away and you
become near-sighted. It doesn't go away.
It worsens over time. So good job, Grandma.
- And it'll make you go cross-eyed.
- No, Grandma, not cross-eyed! I just gave you credit!
- Snacking all day will ruin your appetite for dinner.
But I don't believe that's true because snacking all day
just says to me, be more eat, eat dinner, I'm ready.
I like snacking.
- Grandma just likes snacking. I love snacking too.
If you're eating healthy snacks, you're going to be fine.
That's all I'll say.
- Now don't leave the table before eating your carrots,
because they're good for your eyes.
- Well, they don't make you see better,
but carrots do contain beta carotene, which is vitamin A,
which is important for your eyes.
But it's not like if you have bad vision and you have normal
vitamin levels and you start eating carrots,
it's going to improve. That's not going to happen.
In fact, you may turn orange from all that beta carotene,
if you eat too many carrots.
- Now, walking after a meal will help digestion.
And I know that for a fact.
- I wouldn't necessarily say it helps,
but it is a smart thing to do.
If you just eat a big meal and then plop down and lie down.
The gastric juices that are secreted by your stomach can
actually creep up into your esophagus causing heartburn,
acid reflux symptoms. And you do not want that.
So, Grandma, I agree with you on this one.
- All right, now those of you go who outside with wet hair,
are gonna catch a cold.
- But Grandma, common cold is caused by viruses.
Rhinovirus is a common one, coronavirus is another one.
Why would going outside with wet hair cause that?
Even Bear, Bear's traumatized by that.
You know what?
I wouldn't recommend going outside with wet hair.
It's bad for your hair.
The outside air makes the wetness freeze,
the water in your hair expands.
It can actually make your hair brittle and weaker.
Your hair breaks.
You don't want that. Neither do I.
- Okay. Now don't swim for 30 minutes after eating,
or you get a cramp.
- Okay. A cramp is something I haven't heard before.
I heard that you might throw up,
will you get a cramp? Possibly.
Because if you eat a ton of food,
blood rushes to your stomach,
your parasympathetic nervous system kicks in.
It wants to rest. It wants to digest.
And then all of a sudden you start swimming and you're
moving all these muscles, and you need more circulation
there. The blood leaves the stomach, the stomach can cramp.
Or, maybe you're not getting enough blood flow
to the muscles and your muscles can cramp.
I don't know which cramp Grandma's talking about,
but it can happen.
- Drinking 7UP can ease this upset stomach,
because I know, 'cause I have a lot of upset stomachs.
I have a lot of 7UPs.
- I cannot even begin to come up or fathom a reason
why 7UP would help a stomach ache.
First of all, 7UP contains caffeine,
which can irritate your stomach lining,
cause more acid secretion, and cause more stomach ache.
It also has a ton of sugar in it,
which is pro-inflammatory. Like, if you like the bubbles,
just drink club soda,
without all the caffeine and added sugar.
I think this is soda industry lobbying at its finest.
They've even managed to convince Grandma to stock up on 7UP.
Don't do it.
Do not do it.
Sorry, 7UP.
Guess I just lost that sponsorship.
Oh, well.
- Flu shot can actually give you the flu.
I, I don't think so, but it's necessary to have one.
- Grandma's correct here!
The flu shot cannot give you the flu.
It just physically can't. It can't happen.
Could you get the flu at the same time you get the flu shot,
'cause it takes a little while to kick in? Yes.
By getting the flu shot, you can have an immune response
that might make you feel a little bit tired.
Maybe have a little headache,
maybe have a little bit elevation in your temperature,
which makes you think you have the flu.
You don't have the flu. You're good.
- Sucking on your thumb will cause buck teeth.
I think that is true. And so don't do it.
- Sucking on your thumb, past a certain age,
can cause jaw and tooth deformities like
buck teeth. Grandma is correct on this,
but a lot of kids do this.
I've seen numbers climb as high as 70, 80%.
Ah, sometimes we're doing like the prenatal ultrasounds and
you'll see the baby's thumb in its mouth. Even in utero.
It's fine. That's, that's their self-soothing mechanism,
but you should start to discourage it at around age four
because then it could start impacting
the permanent teeth that are coming in.
Grandma, stamp of approval on that one.
We talked to Grandma, let's talk to kids.
Actually, they're going to teach me about periods.
Let's see what they know.
Huge thank you to Grandma Bobbe,
and grandson Matthew, for being in this video.
As always...
Grandma, you do it.
- Okay. Now, stay happy and healthy.
(upbeat music)
