It’s POTS awareness day—a blood flow problem common after Covid.
POTS can be subtle—I often wonder how many people who feel rundown, anxious or distracted have this treatable condition.
Main criteria is heart rate going up >30bpm when going from laying down to standing—smthg you can check at home!

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)
