You can be heavily pregnant and not realise. Cryptic pregnancies aren’t that uncommon, with 1 in 500 not recognised until at least halfway through and 1 in 2,500 not known until labour starts.

Yeah yeah, it's all my fault!

Bacteria on your skin cause your itches. Specifically, bacteria known as Staphylococcus aureus can release a chemical that activates a protein in our nerves. This sends a signal from our skin to our brains, which our brain perceives as an itch.

But this is fun! So.. Thanks!!

Starfish don’t have bodies. Along with other echinoderms (think sea urchins and sand dollars), their entire bodies are technically classed as heads.
