Talking Baby Sloth Says Happy International Sloth Day (Video)

This video stars a very sleepy baby sloth who is trying to wish you happy international sloth day (October 19th) but he can't stop yawning.

Sloths are one of nature's most misunderstood creatures. Often derided as lazy and stupid, they are in fact extremely successful and being slow and sleepy is the key to their success. As busy bipedal apes, I have always felt we have much to learn from the humble sloth and his energy-saving lifestyle, which is why I founded the Sloth Appreciation Society.

And it seems I was right. Scientists at the University of Rochester have just discovered how incredibly important sleep is to humans. In a paper published this week they reveal for the first time that sleep is essential for cleansing the brain of toxins that cause Alzheimer's and other neurological disorders. Sleep allows the brain to have a spring clean and put out the trash.

So make like a sloth this International Sloth Day and have an extra long lie in. It will be good for your brain.
