Many people have a certain affection for Iron, it is key to industrial civilization. It lives in our blood, though our blood is a relatively smaller percentage of Iron. It is responsible for delivering life giving oxygen to our cells. It's the key element to the hemoglobin of our blood. Some people have referred to the chlorophyll in plants as "plant blood." Which is green and the key element of "plant bloody" or chlorophyll is magnesium. Many crustaceans if not all of them have blue blood. Blue blooded creatures, the key element to their blood hemoglobin is copper based.

Horseshoe crabs are actually exploited for their blood. Turns out blue blood has some vaccine vital applications for LDL that is refined from blue blood. This video explains that all quite well --> . Video provided by You Tube Channel (Business Insider).

Typically I don't like starting off going off topic, LOL, but rabbit holes are there to go down.

Blood is actually magnetic, though maybe not in a way you might expect. This next video puts some light on that situation. --> . Video provided by You Tube Channel (Brainiac75).

Iron is the flagship element when it comes to magnets. When people refer to ferrous metals Iron is typically the first that comes to mind, and that is rightfully so because the word ferrous comes from the Latin word for Iron which is Ferrum.

This is why Iron is listed as "Fe" on the periodic table.

Iron is number 26 on the Periodic table. And the next two metals to the right of it also happen to be magnetic. 27 Cobalt and 28 Nickle. Strange enough, because Cobalt and Nickle are magnetic they refer to them as ferrous metals, at the same time either one of those two are Iron, but I guess via proximity. And I do believe there are some other elements on the table that are magnetic, at the bottom some place, I remember it mentioned in a video but don't remember which element(s) they were.

Note: Manganese is right beside Iron on the periodic table but to the left instead of the right, it's number 25. Interesting thing about it is elemental Manganese isn't magnetic, however manganese-sulfate does happen to be magnetic! Something to do with it being right in the center of the transition metals and having 5 D-electrons.

Years ago, my friend had a fainting spell at a dinner. She did manage to wake up from it rather fast, but when she went and got checked out it turned out she was lacking in Iron.

Years later on, I was at my Grandma's house and I mentioned I was tired, so my Grandma insisted I take some of her Iron pills. I don't think I was actually Iron deficient, but her Iron pills did turn my stool a black color.

This video covers anemia, which is caused either by Iron deficiency or B12 deficiency. Interesting thing about Vit B12 is that it has no Iron in it, but it does have Cobalt in it.
B12 =(C₆₃H₈₈CoN₁₄O₁₄P). The video also mentions folate which is also called Vitamin B9 or (C19H19N7O6) I pulled this quote right off of wikipedia --> "Folate, also known as vitamin B₉ and folacin, is one of the B vitamins. Manufactured folic acid, which is converted into folate by the body, is used as a dietary supplement and in food fortification as it is more stable during processing and storage." Oh yeah, and here is the video provided by You Tube Channel (FuseSchool - Global Education) -->

This video covers signs of iron deficiency provided by You Tube Channel (Body Hub) --> It mentions the vital role of Iron in the immune system, especially important these days I think.

This next video is interesting, and it turns out there is a range of causes in terms of anemia.
This guy breaks that all down for us in extreme detail, rather long video, but if you care to really zoom in on anemia here it is. From You Tube Channel (Ninja Nerd) --> . I'll tell you this for free, this guy really knows his shit.

Turns out, Iron deficiency is only one cause of anemia, so adding Iron wouldn't always be a solution, really depends on what exact thing a person is dealing with. And isn't it typical, all these problems the human body encounters due to what they call auto immune disease. And isn't it typical how the origins of auto immune diseases always seem so elusive?

Red Blood cells, what could be more important? Absolutely vital. Note: Red blood cells seem to be the target of modern day vaccinations.

Here is a tonic people could make to help out their blood. I guess this stuff does a few good things, helps fight cancer, cleans blood, builds blood back up, might be worth it, blood is pretty important, vital system.

One rather exciting application for Iron-Oxide is thermite, with the help of some aluminium. Technically it doesn't always explode, but sometimes I have seen it explode, :). For all you explosion addicts out there that enjoy things that go boom.

This short video here has a nice thermite explosion, they used up allot of it to create this bang! So enjoy! Provided by You Tube channel (kotton87) -->

This one here is quite exciting as well, thermite burns at about 2500 degree celsius, 2773.15 Kelvin or 4532 fahrenheit! This stuff literally melts right though a car engine! Impressive! Video provided by You Tube Channel (Baltaszar) -->

This video covers some of the history of Iron used in steel, and some of the different types of steel there are. Who knew Mars was red due to all the Iron-Oxide on it's surface? The Earth's core is loaded with Iron and is responsible for it's life sustaining magnetic pole. Thirty-two percent of Earth composition is Iron! Lots of interesting bits in this video.

This video shows us common iron reactions, nothing live all theory, but interesting none the less. Who knew there was such a thing as Iron 2 Iodide ? Video provided by You Tube Channel (FuseSchool - Global Education)-->

No video tour would be complete without the Periodic Table of Videos contribution. Nothing new really covered, but I love this You Tube Channel, can't leave it out -->

One time when I was fairly young, I had a noise bleed, and I was letting the blood just fall into the sink, the sink filled up with blood. And there just happened to be some hydrogen peroxide under the counter, so I though, I should disinfect the sink, so I added hydrogen peroxide to the blood, the reaction was actually pretty impressive. This video shows just that, provided by You Tube Channel (CrazyRussianHacker) -->

A comment left on by You Tube user (prashant saxena) regarding this video explains why this happens: " The reason why it foams is because blood and cells contain an enzyme called catalase.When the catalase comes in contact with hydrogen peroxide, it turns the hydrogen peroxide (H2O2) into water (H2O) and oxygen gas (O2).Catalase does this extremely efficiently -- up to 200,000 reactions per second. The bubbles you see in the foam are pure oxygen bubbles being created by the catalase. Try putting a little hydrogen peroxide on a cut potato and it will do the same thing for the same reason -- catalase in the damaged potato cells reacts with the hydrogen peroxide."

Here's a little footage of Iron-man kicking some ass, laying down some justice. Little off topic, but you don't cover Iron without bringing up Iron-Man! Video provided by You Tube Channel (TopMovieClips) -->

I was at a family reunion once, and I put on a wet suite and spend lots of time on the open lake. My arms and legs turned red. One of my more entertaining relatives gave me the nickname Iron-man! I got a kick out of that.
