VAMPIRE MICE

There has always been a question of why the heart of the island, which is the life force that has the properties to give life, death and rebirth, needs to be protected from human beings.

It is one of those common sense questions that has no logical answer.

Which gets us to "vampire mice." 

New medical research studies published in Science and Nature Medicine state that older mice given blood from younger rodents quickly become rejuvenated, exhibiting greater strength and memory. The concept of injecting older mice with younger blood leads to immortal comparisons with literary vampires.

The studies stated that a protein called GDF11 — also found in human blood — is behind the rejuvenating properties.  Concentration of the substance appears to decline in advanced years. 

An an unrelated study, aging and death was tied to a person's lack of blood stem cells which also decline as one ages.

These findings could be used to treat age-related diseases such as dementia and Alzheimer’s. However, some scientists warn that stimulating the rapid regrowth of cells could possibly lead to increased risks of cancer.

The concept of "new blood" is an old phrase that embraces change. But now it has the meaning of prolonging life.

So why were guardians needed to "protect" the island? Perhaps, it was another red herring. The concept was not to protect the island but to bring young human beings to the island so the mythical light force (if it was a being) could feast upon the blood of the young to remain rejuvenated and strong.

If you add the pre-Columbian rituals of the ancient Mayan civilization which were very keen on human blood and blood sacrifices, there may be something to this notion of young blood. The Mayans used sacrifices, including small children, as a means to appease their gods. They believed that the gods provided them with everything, including rain and good harvests. In order to keep the cycle of life going, the Mayans had to offer blood to those gods.

Is it possible that the LOST survivors were used like cattle to feed the blood requirements of an alien island being? Was Jacob not the guardian of the island, but the person in charge of procuring the next candidates for the blood feast? This would also explain why there was no moral compass on the island. Those living on it lived and died in a brutal fashion. The island itself conformed its power into smoke monsters to take the appearance of humans in order to have those on the island have more conflict and blood shed. And if it was not at the level the island wanted, the smoke monster would rage out of control like it did at the Temple in Season 6.

If the characters on the island were only brought there to feed the blood lust of the island's heart, that puts LOST into a whole new, creepy perspective.
