Flamingoes aren’t born pink. They actually come into the world with grey/white feathers and only develop a pinkish hue after starting a diet of brine shrimp and blue-green algae.

Using radiometric dating, scientists have discovered that the Earth is 4.54 billion years old (give or take 50 million years). This makes our planet half the age of the Milky Way Galaxy (11-13 billion years old) and around a third of the age of the Universe (10-15 billion years old).

Your brain burns 400-500 calories a day. That’s about a fifth of your total energy requirements. Most of this is concerned with the largely automatic process of controlling your muscles and processing sensory input, although some studies show solving tricky problems increases your brain’s metabolic requirements too.
