- I'm excited to get into those comments
and answer your questions.
Huge thanks to Google Maps for sponsoring a portion
of this video.
Why can't you swallow while your mouth is open?
Probably has something to do with your soft palate or
your tongue or a negative pressure that needs to be created.
I don't know, I'm gonna guess it's something with a muscle,
or epiglottis being closed, I don't know.
The answer is, I don't know.
Don't be afraid to say 'I don't know'.
Is there a specific rule preventing a doctor
from donating their own organs or bone marrow to a patient?
I don't think that there's any rule in place for that.
I wouldn't even see what would be wrong with that.
Why do I sneeze more when I have a cold?
Well, that has something to do with the irritation
of the airways.
Remember you have little hair follicles that actually
try and prevent and catch certain allergens,
viral particles, mucus, and when they get irritated
it triggers the sneeze reflex and encourages you to
projectile sneeze all those things out.
It's actually a protective mechanism.
Macks from YouTube, "Is there a health benefit to eating
a piece of meat that's cooked rare verse well done?"
In healthcare, everything has risk verse reward.
When you're cooking something rare, you're getting
less harmful compounds created by the flame interacting
with the food.
So you're getting less PHs less HCAs,
but then when it's rare, you're also potentially
exposing yourself to some extra bacterias.
Ideally, it's better to find a middle ground where
you're cooking the meat to the recommended temperature to
kill the possible bacteria that's there, but not overcook it
to the point where you're creating harmful compounds.
"If you get a testicle transplant, I think it's
testicular transplant, and got someone pregnant
who would be the biological father?"
Wait, did they do testicular transplant?
This is, see, you learn something new every day.
Let's see, testicular transplant.
Oh my god, look at this, New York Times,
"Surgeons transplant a testicle from one brother
to his twin."
Oh my god. I don't know.
If that's, if your only testicles are ones that have been
donated to you they're probably genetically,
the other persons.
I don't know.
"At the drugstore they offer Advil
and then Advil Extra Strength, why would I not want
to use a stronger option?"
Well, extra strength usually just means
that the dosage per pill is higher.
You could technically just take more pills
of the regular strength one,
and it'll be the same as extra strength.
When you take more of a dose of a medicine,
you actually increase the rate of side effects
and there is a a tapering off effect where you're not
gonna get more benefit when you take more dose,
but you will have more rates of side effects.
So you kind of have to balance that.
"Bro wtf is raw milk, isn't all milk raw?"
It starts off as raw, but the milk you get at like
the supermarket is usually pasteurized milk.
So it's like heat treated and the bacteria is killed.
That's why in most cases when yogurt is pasteurized a lot of
the bacteria gets killed, they add probiotics to the yogurt.
"Can STIs survive in toilet water? Would toilet water
splashing up into my genitals infect me?"
You know what's interesting?
I just had a patient that brought this up to me
this past week.
For some reason, young folks when they feel embarrassed
coming to see a doctor and talk about their
sexual experiences, they say that they believe
this happened as a result of toilet water splashing up
into their genitals.
Look, technically you could probably make an argument
that this could happen.
The chance of this happening versus it being from an STI,
like transmitted through sex, is almost nil.
So I would say it's probably sexually transmitted,
and at the same time, you shouldn't be embarrassed the fact
that you are sexually active, and you shouldn't be
embarrassed to speak to your doctor about it,
'cause we're not there to judge you, we're there to help,
and we can only help you to the best of our abilities
when you're being honest and truthful.
"What are your thoughts about nasal irrigation
when you have a cold? Does it help?"
I love nasal irrigation with saline sprays.
That's like my go-to recommendation for my patients.
The nasal saline will clean out mucus,
will get rid of allergens, clear out viral particles.
All in all, a positive thing when you have a cold,
it's the same way that we recommend salt water gargles,
but this is even better 'cause it's going directly
into your nasal passageways. So I'm a fan.
Back to the questions in just a second.
But first I wanna thank Google Maps for sponsoring
this part of the video.
If you didn't know, they provide maps in 99% of
the world's countries and territories,
which is why I've been using Google Maps
for years when traveling.
But there's actually a ton of uses for Google Maps
when I'm at home, especially lists, whenever friends visit
me in New York City, they always need recommendations
of where to eat.
I'm actually the best at this because I love to eat out.
Using the Google Maps list feature, I'm able to access my
favorite restaurants in the area where they're staying.
I've actually labeled the list using their new
emoji feature to categorize cuisines a bit easier.
Then boom, right from the app, I'm able to share the list,
and get my friends fed with some yummy, yummy eats.
If you're planning to travel, perhaps in New York City,
Google Maps has an awesome new feature that can
make your next visit even more fun and easy,
Immersive View.
It will help you confidently decide where to explore
using interactive 3D previews, weather conditions,
traffic, and other info.
For example, folks are obsessed with visiting
Washington Square Park, but it can be difficult to find
if you're in from out of town, thanks to Immersive View,
you can get a 3D look at what the park looks like
and all the different ways to get there,
so you can know before you go.

Thanks again to Google Maps for sponsoring
this part of the video.
Now let's get back to your questions.
"I saw a video of a doctor on TikTok saying that people who
have a dark line in their nail may have cancer. Is it true?"
This is true.
You could have cancer if you have a dark line
going through your nail, it's called a subungual melanoma.
But what I will say is there are other causes
of dark lines in your nails that are not cancer.
So don't assume when you have a dark line
in your nails that it is cancer.
Instead use it as a reason to go seek out medical advice
and check with your doctor if this is something
to be concerned with.
"Should I eat protein before or after my workout?"
I think the general consensus is to eat after your workout.
And I know we talk about that protein window quite often,
and when I say protein window, it's like eating
and getting protein, and maybe even some sugar
immediately past a workout in order to get maximal benefit
from like insulin release and getting the nutrients
into cells.
There's some truth to that, but there's also
some non-truth to that.
And the non-truth is that while it is ideal to eat
after your workout within that window, that impact of
eating in the window, that benefit usually goes away
after you've been training for a long period of time.
"What happens if you resuscitate someone who has a DNR?
Will you get fired?"
I mean, if this is a genuine accident, maybe not.
I mean, it'll be situationally dependent.
There is a world where a family member could sue you,
or even the patient could sue you.
"Are there different kinds of Heimlich maneuvers you're
supposed to do depending on the person? Like for a baby
versus average adult versus heavy person?"
Yeah, absolutely, especially for babies versus adults.
You gotta think about a baby's ability to regurgitate
an object and the way that you're gonna position them
is gonna be much different than an adult.
And with a baby, you wanna start with back taps
before you start doing a proper Heimlich maneuver.
And if you full on press on a baby like this,
you could really hurt the baby.
So, it's a different mechanism.
But here are the ones demonstrated for babies versus adults.
"Why do they call that part of your arm the funny bone?
And why does it hurt in the weird way when it gets hit?
The rest of my arm doesn't feel that way when
I bang it on something, so why that spot?"
Okay, the funny bone is not a bone.
There's a nerve that runs all the way from your neck
all the way to your pinky called the ulnar nerve,
and it runs inside this groove here called the ulnar groove.
Now, this nerve is really protected.
It's protected well by muscle, by other tissue, by fat,
all the way, except in this little canal.
I think this is like one of the the longest portions
of nerve that is unprotected in your body.
When you hit that area, you can actually feel the sensation,
the tingles, the weirdness. That's nerve pain.
Nerve pain is very unique from other types of aches.
So that's why it feels funny, but also it's near
the humorous, so I guess you could say it's also funny.
"Is it bad to sleep with a fan blowing directly on you?"
I actually think that it's not ideal.
Think about it this way, if you're blowing a fan
that means it's probably hot in the room.
When you're hot, you start to sweat, and when you sweat
the purpose of that is so that the sweat evaporates
and cools the surface of the skin.
And now the fan speeds that whole process up
and as a result that area gets extra cool,
and when it gets extra cool, your body redirects blood away
from that area, therefore that area gets less circulation.
So it's not unusual if you have a fan or air conditioner
blowing on one side of your neck to wake up
with a stiff neck.
In fact, one of the first questions I ask when a patient
comes in with an acute stiff neck is,
"Were you driving with the window open on a cold day?" or
"Did you sleep near an air conditioner or an open window?"
The red heavy, YouTube, "This is silly but does sex count
as exercise?"
It does count as exercise.
Anything that gets your heart rate up is technically
gonna be exercise, and research points to most people
burning only about a hundred calories
during like an average 20 minute session.
Those numbers are roundabout so,
you're not burning a ton of calories.
Think about it, like a Snickers bar has like
350 calories or something, so you're not even burning
a third of a Snickers bar when you have sex.
"What about taking a hot bath when running a fever?"
I don't understand the whole bath thing when having a fever.
Some people think getting into a cold bath
will help cool you down, don't do that.
If you get into a really cold tub in the midst of a fever,
your body can go into shock, that could be problematic.
Going into a hot bath doesn't necessarily make it better.
Just allow your body to thermoregulate as it needs to.
Remember when you get into a hot tub and you have a fever,
okay, maybe it helps your body get warmer
without needing to develop chills.
When you come out of the tub, you're gonna get really cold,
because that's the natural state of things.
You're not gonna right away get into like an
uber warm environment and therefore you're gonna confuse
your body and make it difficult.
So just stay out of water as much as you can unless,
you're really dirty and you need to clean yourself,
then you could do a quick shower, normal temperature.
Sarah, Gloria, "Why is it that when someone who has
poor vision takes off their glasses it becomes
a little easier to see if they squint?"
You're actually creating a focus, and you're able to
see easier when you're focused, you're concentrating
that light on the back of your retina.
"Why does one of my ankles crack more than the other?"
I mean, this happens quite often.
Patients come in and they have no symptoms other than
sometimes their knees or joints make some noise,
and in most instances it's fine.
There's nothing scary going on.
And yeah, joints make noise and this is okay.
Sometimes it can be problematic, 'cause it's telling me
that there's damage going on, but that is such a rare
exception that for most of my patients I just say,
"Oh, yeah, my knees crack too, and I bend down
and they can hear my knees crack as well."
And why does one crack more than the other?
Maybe you have a little excess scar tissue,
maybe one side is slightly longer.
Maybe anatomically your bones are slightly different.
So do I have the perfect answer? No.
But unless it's coming with symptoms,
or it's progressively getting worse I wouldn't necessarily
jump with alarm bells.
"What if someone as big as Andre, the giant needed CPR?
Could the average person perform it on him
or would extra measures need to be taken?"
How big is Andre the giant?
- [Off Camera] He's like seven feet, 500 pounds.
- My suspicion is if you're a small person performing CPR
on a seven foot five, 500 pound person
you would not be able to compress the chest cavity enough
to make the heart pump blood to the rest of the body.
Therefore, extra measures would need to be taken.
Perhaps one of those robots that I've seen
that they're testing out in the field that does CPR,
maybe one of those robots could do it.
"What? No peewoop at the end of the intro."
Yeah, so I don't peewoop after every intro,
and that's because some videos are more serious
and it feels weird to say peewoop when I'm talking
about a very serious topic.
I'm also curious what is the current stance of peewoop?
Are you for it? Are you against it?
Are you confused by it?
Leave me a comment, I'm curious.
You asked me questions, but so do people on the street.
