A healthy person usually has a platelet count of 150,000 to 400,000. You have thrombocytopenia if your number falls under 150,000. If you're wondering what the long name means, here's how it breaks down: thrombocytes are your platelets and penia means you don't have enough of something.
The Perseids are active from July 13 to August 26, according to the American Meteor Society, a nonprofit scientific organization that supports the research of astronomers, but the meteor shower peaks between August 12-13.
In May, that meteor shower is known as the Eta Aquarids, while in October it's known as the Orionids. This year's Orionid meteor shower arrives around the night of Oct. 21-22, just as Earth is plunging through the remnants of Halley's Comet on our own orbit around the Sun.
