Does Giving Blood Make You Healthier?
www.seeker.com...
"Some donors believe that donating blood actually makes them healthier. That line of thinking is correlated with medical bloodletting. Once a popular treatment for many diseases all over the world, it hasn't been widely used since the late 19th Century. Although bloodletting has been largely discredited in the scientific community, a similar procedure became popular with the iron-store hypothesis, based on the idea that too much iron in the blood can increase our risk of cancer and heart disease."
Blood from Human Babies, Teens Rejuvenates Old Mice
www.seeker.com...
"Aging is a killer. Incidence rates for heart disease, cancer, kidney disease and dementia all skyrocket as people reach their 70s and 80s. There's no cure for getting old, but there may be a surprising simple, albeit somewhat medieval, way to turn back the body's internal clock and reverse the deadly effects of degenerative diseases."
How Much Blood Is in the Human Body?
www.livescience...
"There's enough blood in the human body to fill a bit more than a 1-gallon milk jug. The average adult has about 1.2 to 1.5 gallons (4.5 to 5.5 liters) of blood circulating inside their body, said Dr. Daniel Landau, a hematologist and oncologist at the University of Florida Cancer Center - Orlando Health. If you had no blood, you'd weigh 8 to 10 percent less. (Of course, you wouldn't be alive, either.) So, for example, in a person weighing 120 lbs. (54 kilograms), blood takes up about 9.6 to 12 lbs. (4.4 to 5.4 kg)."

Thumbs up to Dr. Dad

[@TheUglyGnome]

Yep! Dad is scientifically literal. He measures things in liters and grams unlike the daughter.

[@Eclipse-qc7qo]

Jeffrey Dai

[@JdotCarver]

He must be proud. 👍

[@将軍九八.彁]

Strong women have strong fathers.

[@TrekkieBrie]

"Doctor Dad" is my new favorite thing she's said :) lol

[@ozdergekko]

Oh, Amy. We all love her dearly. Or so.

[@mathbarr]

I lost 4/5th of my blood over time and lived. Of course, when my blood test results came back, they immediately sent me to the hospital to get a transfusion. And I wasn't really fully functional, as I had barely any energy.

[@seecanon5840]

I lost down to a volume of 3 and had a 5 bag transfusion. I hurt, ached and was very tired.

[@damionmurray8244]

"Doctor Dad"...that brought a smile to my face.

[@nidhinanil.]

Doc.Dad : )

[@shekool18]

Please keep this format, Seeker. It is the one we are all used to before, I think, Discovery made you give up the 'Dnews' name. I have been watching every single video that you post for 4 years now. You made me smarter and I am now an even bigger fun of science. Please keep all the amazing hosts and do not give up on making this amazing videos.

[@JailanSimon]

How long would it take to regain 2 thirds of your blood ?

[@cup_check_official]

WAIT. DID SHE SAY DOCTOR DAD???? 3:02

[@quinius173]

She said it more than once.

[@mubaraka1417]

Quinius its because the doctor is her dad

[@quinius173]

Of course I know that. Just that Dr. Dad is a weird phrase.

[@mubaraka1417]

Quinius Depends on the way you see it

[@Mostafa_Akbary]

I want to be examined by Dr. Dad!

[@jasontempest4233]

My fav blood fact? Something new I recently found out is that I'm AB negative, which is very rare at about 1%, however I can take ANY blood type in a transfusion and only other AB negative people can take mine. That makes my blood pretty useless I guess.

[@djp1234]

what is a a pint? that's a unit of measurement in a bar, not a hospital

[@TLOKkiante]

A pint is 2 cups.

[@545Cease]

Might want to check latest research on blood production

[@realrough]

Lovely Doctor dad ! Thanks Milady

[@RaNdOmPlAyS]

i love this girls hairr😍✌🏻

[@mrj3222]

Where do u find such crazy topics???

[@karkinissan]

Editors can you respond, why are Seeker videos so smooth?? They're not even 60fps yet they feel like it.

[@Courtneysid]

Editor here. Not totally sure. We use the default youtube 1080 29.97 setting in Premiere. Original footage is shot on 4k.

[@karkinissan]

haha. But you think the video looks smoother than others too right?

[@alanmarston8612]

Amy, Are you also with Seeker now as previous?

[@lazyperfectionist1]

My favorite blood fact? A tourniquet is useful in _many_ cases, but _not_ with a head wound.

[@exmythos7318]

so we lose more than one-third when we die from blood lost after an accident ?

[@bazrazin1]

are there bacteria /viruses in blood of a healthy person.

[@TheInselaffen]

Reequilabrate is not a word.

[@Hirnlappen]

Pleasant surprise seeing Amy on this channel :-) She really does a nice job!

[@retak4110]

What is a pint

[@anqervr2750]

i just lost a lot of blood and i feel tired

[@kevinhuang379]

Wait why did you guys change your name to Seeker

[@ch1ll1add.25]

What's the song name in the background

[@FoundAlaskaYoung]

Go Dr. Dad!

[@ECytchannel]

Yeah thats all good and all but, would you rather 'survive' or live ?

[@merlincnrad5385]

Thermostats keep evrything on the right level?

[@benschofield1361]

Amy!

[@tobyclaxton7241]

Hi

[@charliesgotaguitar]

It's really cute that you asked your dad as an expert :D

[@heavyjunkops]

With an adequate vacuuming system, the human body can be drained of all it's blood in as little as 7 seconds.

[@BrandonAngelDragon]

Can NowThis, a.k.a. used-to-be Seeker Daily, a.k.a. -used-to-be Test Tube news survive with only One-Third of viewers and nearly Three Thirds Dislikes?

[@mreyeball3085]

Dads know most

[@LamsterLou123]

hannah lost alotta damn blood

[@MarcusGFilms]

Someone tell me what happened to DNews!?

[@TheUnmunchable]

If Plasma replenishes so quickly why can you only donate plasma every two weeks?

[@Jack-rp6zy]

Okay Seeker, first the story on cannibalism and the caloric intake it provides, and now a story on the minimum amount of blood a human can survive on. What's going on, is there something you're trying to tell us?

[@michaeldurfee3061]

How do your bangs stay so still it’s like they’re paused.

[@iurope4834]

Wait does this stand for children too Guess if yes people can survive with just over half a litreof blood

[@vanshsinghal6779]

what if we accidently creat a crack in fabric of space

[@jkm7983]

0:21 she said gallons but it says liters

[@thezocker071]

its for people like me that dont know how much a gallon is

[@oscaremoralesp28]

The ad-pocalypse is hitting them so hard they have to use family members as experts for the videos.

[@radioactivegamez305]

You can heal up with golden apples

[@tmbgfan1234]

SOOOO many a-boots.

[@chandrapandey9014]

31

[@Spooksandooks]

why isn't the same true with the lungs liver or kidney. And yes my channel .. 😂

[@samgeorge4798]

I get the first sentence but why say "and yes my Chanel"

[@bruhkris20]

Sam George he said channel, not Chanel.

[@alex.harrison]

Spooksandooks - it is the same, arguably even more so. You can survive (though not enjoyably) with only 10% kidney function. Likewise, less than one lung and with marked deterioration in liver function. But what does "survive" mean? Such impaired organ function won't kill someone in hours, but it inevitably shaves many many years (often decades) off their life

[@tamu7243]

I bet everyone that were watching Seeker daily, unsubscribed to Now This, and is now here.

[@thetechnoking]

St nd Rd = Standard

[@ozdergekko]

[@ClockworkRBLX]

Just shut up and kiss me!

[@supernova6177]

is that ur wife

[@KZXten]

Very cool stuff...Thanks! Did you know that the Bible speaks of the importance of blood. 1) Without the shedding of blood there is no remission of sins. 2) Jesus Christ payed our sin debt by the shedding of his blood...He Died in our place...He was buried and rose again on the third day to everlasting life...THAT'S THE GOSPEL! Trust in Jesus today...Receive Salvation through faith in Jesus Christ.

[@mahammad]

[@zeratulrus142]

[@joshcat7042]

lol i can see a fight spawning

[@OzymandiasFGC]

alik alik I really dislike people presenting opinions and beliefs as fact.

[@charbladex]

0:15 wait I'm American and we don't even use gallons as the unit of measurement for blood...

[@gustavalbrektson8046]

Charbladex I wonder what that text in the bottom left says...

[@kotryna5682]

Scientists generally use the metric system, regardless of their country, but most viewers here aren't scientists and are American.

[@cup_check_official]

My question is: Can you survive with only One-Third of the bacteria in your body? Considering they play an important role in digestion and various other things :3

[@conman1395]

No, most likely not. Working with only 1/3 of the flora in your GI system some would make you miserable and likely very malnourished due to the effect on your digestion. 1/3 of all the bacteria in your body will weaken the defense against bad bacteria. It will require your immune system to work harder and it'll probably lose the fight. Eventually the bad bacteria will take over.

[@ozdergekko]

plus it would leave your mucous membranes and your skin in general very susceptible to "evil" bacteria and fungi.

[@thomasmajewski1562]

Most likely yes. If you have taken any oral anti-biotic for an infection you most likely have wiped out a large majority of bacteria in your gut before. Which will be replenished in a matter of days. It may effect your ability to break down digest some of the nutrients in your diet, but you can survive several weeks without eating. So the loss of nutrient intake over some days would be survivable.

[@conman1395]

Thomas Majewski that's correct, but I was speaking given that 1/3 of your bacteria stays at that level. Bacteria reproduce quickly enough that in reality you would survive. Your just be gassy.

[@michaeldaugustine9249]

You can survive with nearly no bacteria in your intestines for a short time. That's what happens when you take broad-spectrum antibiotics, and the main result is explosive diarrhea.. Losing the bacteria in your mouth will probably cause thrush (also a common side effect of antibiotics). And losing the bacteria on your skin will make you more susceptible to fungal infections and acne, but on the positive side it will also reduce your BO.

[@mybackhurts7020]

Dr. daddy says if it hurts don't do it

[@francescofrosolini4637]

well in video games it works

[@MW-qt1ml]

Amy is kinda hot

[@bigmike9128]

Saint Jiub no kinda about it she is just hot and fine.

[@sicfxmusic]

kinda my ass

[@gerRule]

Check out her channel Vintage Space ( ͡° ͜ʖ ͡°)

[@bakersbread104]

dr.dad "what are you intentions with my daughter"

[@Alexus00712]

To look at her for academic purposes

[@hodlface4320]

thats why women dont die lmao

[@RayQns]

I have this disease called sickle cell e. It lowers all of my hemoglobin and can be very fatal. Lucky for me the only fatal thing that happened to me was when I was seven I had pain that was off the charts in my back and stomach. It made feel depressed and wanting to kill my self. It’s still stays with me and I hope it doesn’t happen again.

[@HUNVilly]

Gallon, pint... ok

[@AifDaimon]

"According to Doctor Dad,..." 😂 😂 😂 😂 you're lucky to have a direct source of information when making episodes related to blood

[@rsher7369]

I think her hair is bleeding

[@nathanroon6961]

Thanks Doctor Dad!

[@ブィブィでーす]

hannah baker flashbacks

[@z-army481]

amy finna hot

[@TheKasimkage]

"Doctor Dad" has to be the cutest thing I've heard all day. I love it!

[@ratgreen]

I just had my wisdom teeth removed literally 4 hours ago. I just got back from hospital. I won't stop bleeding so this video is extremely relevant

[@WaterspoutsOfTheDeep]

You are supposed to be biting down on the gauze for a long time. You shouldn't notice it bleeding if you are doing that... because it wont be.

[@asvarien]

How would your body adapt to the loss of blood pressure due to loss of 2/3 of blood volume?

[@feniovic]

By reabsorbing water and electrolytes, basically. On long term, your body will continue to create as many red blood cells as he possibly can, even throwing immature forms to circulation, but on short term, kidneys work to mantein BP stable with wather, sodium and by vasoconstraction.

[@sciyay]

Thanks body :)

[@applepie55555]

Nothing special, crips do this everytime.

[@gerRule]

Wait. What? Does Amy regularly do this???

[@trulyinfamous]

I get a bloody nose and I feel all numb and tingly. I hate that feeling so much.

[@ShawnRavenfire]

This is excellent news for vampires.

[@braveansari]

I donate blood 7 pint in 19 in days should I going to die

[@mnblkjh6757]

Ok red cells carry oxygen so how do cells absorb nutrients from the blood stream

[@jimevans1809]

My body is super awful at keeping my blood where it belongs. I've got a very rare condition where my capillaries open up and let all the plasma and lighter fluids escape into the interstitial spaces in my body, all the while building up hemo-concentration in the circulation. I've just finished another stretch in the ICU. NOT FUN! Any thoughts Dr Dad? I can hook you up with some very good researchers at the NIH in Bethesda.

[@owenmccarthy4994]

check out the pit of the unknown from the clay adventures

[@markh4926]

I woke up around 2am with my heart racing and body sweat. I got out of bed and collapsed three feet from my chair. I called 911 and they came within fifteen minutes while the 911 lady kept talking to me. At the ER they discovered I had almost no blood and they gave me 12 units of blood. The pain was incredible and while the doc was fitting an intravenous in my jugular I was asking for pain meds like the pain was so intense. The nurse said to hold on and try to be calm. I did my best and I guess they got the blood and meds in me. They flew me to a big city hospital where they finally discovered I had upper GI bleeding, internal bleeding. That was two months ago and I am still weak as a kitten.

[@Merrifieldsam]

My favorite "blood fact" is that blood is always blue until it's exposed to oxygen... It's not! I wish people would stop saying/believing this but it seems like it's a common misconception that comes up every so often.

[@jackalvulture]

I'm disappointed in myself for being just a Mr. Person. Being a Dr. Dad must be great.

[@talideon]

-- Hey, dad! -- I didn't spend all those years in medical school for nothing, you know!

[@stupidburp]

please don't sneak spider images in unrelated videos

[@Patch_Z]

I am Dr.acula And I approve with this message.

[@lolioliol360]

Doctor Strange doesnt seem to mind going straight to everest.

[@kevslighthouse]

How funny, I literally JUST studied this stuff in my physiology class.

[@iluke4317]

I just saw the thumbnail,and I thought it was a Minecraft video...

[@oram892]

so that's how Jack survived so long

[@michaeldaugustine9249]

That's why they give you water and a snack after you donate blood.

[@thomasparker8539]

wasn't it recently discovered that are lungs actually play a huge part in the making of blood?
