infinite liver glitch
Time to throw my liver a regeneration party – 3 shots!
I think now Mario wants it.
My liver must be at least 5 from drinking
I’m on a living donor register for anyone who might need a liver transplant.
If Danté's Peak and the Covid outbreak thought me anything it is that the locals will not believe science and just keep going on with their lives (BeCaUsE oF tHe EcOnOmY) and just simply die in the imminent disaster, realising too late that theey should have listened to scientists
Wow
This man comes in this channel also
U are doing good work sir
Please keep it up!!!
I really appreciate your good videos
If a lobe of the liver is removed, it does not grow back. The remaining liver grows larger to compensate.
what if im 2 years old?
My liver may be only 3 but it probably looks like a 90 year olds
I’m 2 – how can my liver be 3?
I’m begging you guys please make a video on the mesopelagic fish biomass
So my liver is in the target demographic for Cocomelon.
Excellent
I'm only 2. How's that possible?
So as you can see, I didn't demolish my liver at age 18. It's not even the same guy
ALRIGHT I'M WATCHING THE VIDEO DESPITE IGNORING IT FOR AN ENTIRE WEEK BUT IT STILL GETTING RECOMMENDED TO ME!
It wasn't bad, but damn that algorithm…
AH, I love our 3 year old livers… With some fava beans and a nice chianti.
I wish Hank had explained the radiocarbon dating technique better. I don’t understand how the proportion of C-14 would really tell us anything, if the ratio is following ideal exponential decay both in and outside the liver. Basically no matter how old your liver is, I would assume the ratio in it would be the same?
None of this makes any sense to me
I'm 35 years old, I have to keep my health for my beloved family
DDT AND BIOMAGNIfication and the scientist and his/her research
Pompeii isn’t mythical. I know YouTubers like ANY comment.
My liver is like 287 don't play with me3
my liver is far from 3 it put in some work when I drank. drank pretty heavily for, more than a frew years. not enough to damage anything much. but 7 months sober and everything is working out.
Hank, why isn't this two separate videos?
The volcano info is super cool and not even mentioned in the title.
Showing LOVE for the channel thank you and have a blessed day everyone
all i have learnt is that the legal drinking age should be 3
So I’m on my 12th liver
Well, I'm going to have another drink… Prost!
I am an esteemed psychologist from Yemen, and I once went into the great pyramid of Giza and found a jug of urine that belonged to Pharaoh Ramesses ii, I drank 50ml of it and had strange dreams for a whole week:-
1- This might sound a bit odd and random, but I have actually dreamt of Zeus mating with a palm tree and begetting an ant that is capable of crawling on the edge of the Higgs Boson!
2- I also dreamt of my mitochondria protesting to break free from my organelles, claiming that nature has enslaved them!
3- On another night of a full moon, I dreamt of Professor Noam Chomsky eating books and regurgitating the field of Modern Linguistics!
4- The funniest dream I ever had, was when I had a vision of a Neanderthal swallowing a whole apple, and it played ping-pong with his heart while passing down his esophagus!
5- This is by no means a joke, but the most disgusting dream I ever had, was of a female's menstruation blood turning into jelly and being marketed by an Oompa Loompa as Halloween treats!
6- I also had a nightmare of riding on a mare at night, with the Pharaoh's personal witch, she was pregnant with a fetus that was eating her placenta!
Do you think my dreams have any philosophical implications at all?
I'm just a little concerned that I'm having a neurological malfunction!
Given that I've heard my neurons conspiring to abandon the dwelling of my skull, things don't seem to be heading in the right direction, ever since!
OKAY I WATCHED THE DAM VIDEO PLEASD JUST LEAVE ME ALONE GAAAAAAAAAAH!!!!
With the recent compilation video about Carbon dating, I think I've heard the Carbon12 vs Carbon14 enough times by now. lol.
Regeneration stays the same or replication?
Hey SciShow whatever happened to Rose Bear don't walk?
Volcanic eruption and earthquake prediction share some similar problems. Both involves the build-up of pressure before the eventual release. There are many signs we can observe and measure, and we can be very sure it's getting there. The amount of stress accumulated can be estimated, and so can be the strength of the ground in the area.
Past certain point, all you need is a (relatively) small break in the ground (slip in the fault), and the movement would cascade and propagate. But when is the big day? Is it tomorrow? The week after? Years later? It is that trigger that we don't know enough to predict.
It is also this unpredictable nature that makes eruption and earthquake hard to study as well, because we can't usually monitor the event closely enough. We can't just set up equipment and had it run for potentially years (and possibly still miss the event). It is hard to 'capture' an event with really good detail.
What those scientist said about the success of the prediction is not just being humble, but actually had some truth in it. All the textbook signs of an impending eruption are there and quite clearly as well (NOT saying their good prediction is trivial, mind you). But it is the fact that the eruption is so closely capture that is the exciting news for the scientific community.
33 donors. Lol a most minimal qualifying sample that could be called a true statistic.
