[00:00:00]Sharks have been swimming in Earth's oceans for over 400 million years. Yet scientists rarely find cancer in them.

[00:00:06]One reason could be their powerful immune system and special genes that repair damaged DNA much better than humans.

[00:00:12]Some sharks, like the Greenland shark, can even live for centuries while aging extremely slowly.

[00:00:17]For years, people believed shark cartilage could cure cancer, but science found no proof of that.

[00:00:23]Still, researchers continue studying sharks because their bodies may hold clues to fighting cancer and slowing aging in humans.
