Earthspeed
"Despite its apparent stately motion, the Earth is pretty nippy: if you stand on the Equator, the speed of its rotation around its own axis is about 1,040mph. This decreases as you approach the poles: stand on either pole and you barely move at all. But remember that as well as spinning, Earth is hurtling around the sun at 67,000mph. Were we able to fly at that speed, we could circle Earth in 20 minutes. The solar system is moving even faster, spinning around the centre of the Milky Way at 492,000mph. Even so, it takes it 225 million years to complete a single orbit (so it has managed 20 in total since the birth of the Sun, and only one since humans evolved)."
" At least a quarter of us respond to bright lights by sneezing. This is called the photic sneeze reflex (from photos, Greek for light) or ACHOO syndrome (Autosomal-dominant Compelling Helio-Ophthalmic Outburst). It was first medically described in 1978 but people have been known to sneeze after looking at the sun since Aristotle; he blamed the effect of heat on the nose. In fact, the disorder is caused by confused signalling from the trigeminal nerve, the one responsible for sensation in the face. Somewhere along its passage to the brain the nerve impulses from around the eye and inside the nose become scrambled, and the brain is tricked into thinking that a visual stimulus is a nasal one. The result is that the body tries to ?expel? the light by sneezing. This surprisingly common trait is inherited. Both men and women can get it and they have a 50:50 chance of passing it on to their children."
