Surprisingly, the universe is packed with unusual facts. Often, reality is stranger than fantasy. Below are a few cool facts to brighten your day.
Let's begin with this: honey has an eternal shelf life. Truth here be told, researchers have discovered jars of honey in ancient Egyptian tombs that are millennia old and still safe to eat. It is due to its distinct chemical composition that makes it impossible for bacteria to survive.
Moving on to animals, the octopus have 3 separate hearts. Two hearts pump blood to the respiratory system, while the other one pumps it to the organs. Interestingly, when an octopus swims, the heart that delivers blood to the body takes a break, which is why they tend to scuttle rather than float.
Here's a weird fact: botanically speaking, bananas are berries, however, raspberries are not. Science is often tricky like that! Additionally, avocados are technically considered fruit, not veggies.
