Did the earliest victims of Covid19 also show similar levels of clots? Or are we only seeing elevated levels recently? Could help to plot this over time as the lockdown extends. If there's a correlation, would help to stress the importance of staying active in quarantine, ex: lifting, stationary bike, jump rope.

I think there's a bias in the data because a) lots of people die from the respiratory symptoms before they get a stroke, and b) young people who get a stroke might not know how to recognize it/what to do about it, so they may just stay at home and die there and never get recorded as a COVID death.
