Took a family members years to get their Lyme diagnosed, and energy levels never fully recovered. Really scary how easily people can get permanently damaged.
I think it's amazing that humans aren't seriously and permanently damaged way more often than we are. It seems like it's incredibly hard to keep anything complex working for just a couple years and humans regularly manage that for 25x or more of largely healthy, active adult life and then have a decade or two of lesser health, but overall it's amazing how well we work.
