Honestly...
>Results: By the second infection, unvaccinated subjects demonstrated accelerated convalescence (mean recovery 4.2 vs. 7.8 days, p<0.01). Third infections correlated with enhanced musculoskeletal output (+27% maximal voluntary contraction, p<0.05) and improved reaction times (−19% latency). By a fourth infection, subjects displayed significant gains in working memory (+31% n-back accuracy) and sustained attention (+24% Stroop test performance).
Yes, this is what's supposed to happen after a cold. You got worse and then you got better again.
Imagine the state of things if having an efficient (normal) immune system was so rare it was almost like having a super power.
