I'm signed to a large-scale (about 4 milion joiners) Covid symptom reporting app and to date I've felt normal each day. Not exciting, but every bit of data is valuable.
Yesterday users of the app were invited to register as possible volunteers for trials of vaccines or other Covid-related experiments, and I did so at once, because it reduces my feeling of being powerless. So I may become a guinea pig.
This reminded me that guinea pig, as a term for a laboratory animal, goes back to 1907 investigations into vitamin C deficiency. Most mammals, laboratory rats for example, can produce their own vitamin C, but humans and guinea pigs can't and must get theirs from what they eat.
