The rainforests of Central and South America are home to some of the most fascinating creatures on Earth, including sloths and howler monkeys.

Today is International Workers’ Day. And what does this have to do with sloths? First, it makes us think about the unfair name of these animals, a form of the word ‘lazy’ in most languages. But even though sloths are not lazy but energy-efficient, it also makes us think about laziness and how in our societies’ overfall, being a little bit idle and slowing down is not permitted. If you have today off, you are probably feeling guilty about it.

Although there are tons of sloth myths on the internet coming from self-appointed sloth experts, there are actually very few scientific studies that have been done on sloths.
