Human Hibernation
Ever wish you could lock yourself inside all winter like a grizzly bear in hibernation? Well, maybe you can! Scientists have discovered that human hibernation is possible. Maybe not for months on end, but research shows that humans have the ability to submit ourselves to deep sleep for days. It usually only happens under extreme conditions, but still pretty crazy!
Mammoth Time
If you think of woolly mammoths as ancient creatures, you might not be able to wrap your head around this next fact. The giant beasts were around a long time, and they were still hanging on when the Great Pyramid of Giza was being constructed in the years of 2580 to 2560 BC. The last known existence of the gigantic creatures was some 4,000 years ago.
