Not to forget those that are actually getting worse, I'd have to agree there's a good percentage that have recovered to some extent. Those 80/90% recovered are probably long gone from here, however. I think a telling distinction is on what basis we make such claims of improvement. Is the improvement viewed from before falling ill or from the awful, lowest point of being sick? In my case, if I had to guess, probably function somewhere around 55/65 percent of pre-illness, but 99.99 better than at the worst. edit: I'm no good at correctly stating stats, probably that last data is more in the vernacular sense, maybe should have said 99 times better than at the worst of it. Yeah, it was pretty bad.
