Here's today's column on the astonishing, ongoing mistreatment of people with #ME/CFS. Please spread it far and wide: the only thing which can break the media's wall of indifference is seeing an article about the issue go viral. Thank you. 1/2 www.theguardian.com/commentisfre...

What Does POTS Stand For?

POSTURAL: Related to the position of your body
ORTHOSTATIC: Related to standing upright
TACHYCARDIA: Increased heart rate

Phoresis is the name for when one organism attaches to another for the purpose of travel, and pea clams (Sphaeriidae) are masters of it. They attach to birds, fish, salamanders, and even aquatic insects like dragonflies or water boatmen to get a ride upstream. Ride on, little clams! (293)
