I'm sure you're right, but it's also true that most whistle-blowers have petty and selfish motives, and that they are often driven by personal grudges (which they tend to have a lot of, since they are generally quarrelsome and problematic people). Deep Throat apparently exposed Watergate because he was bitter about losing a promotion.
It takes an unreasonable person to go up against the system and against the culture of one's organization. These people may not be personally admirable in the way we might like for a Hollywood good-guy/bad-guy story, but that doesn't make whatever revelations they provide less important. Nor does it make it OK to persecute them for it.
Now maybe Dymovsky was arrested for some other shit he was involved in, but given Russia's history with internal critics, that would not be my first guess.
Actually, if a small scratch got infected in 1200 AD, your body's immune system would most likely fight it off and you'd be fine. Just like it would today. Sure, in some cases your immune system might be weak or you might have got a more aggressive bug, and you would end up with septicemia and die (or tetanus, in those pre-vaccine days), but generally a minor infection would not be, and is not, fatal.
I certainly don't advocate living without antibiotics, but if I get a non-serious infection I still wait a few days to let my immune system have a crack at it before I call up a doctor (unless it's worsening or particularly painful, of course).
Hygiene, vaccines and nutrition are very likely nearly as important factors as antibiotics in the rise of life expectancy since the middle ages.
An authority is a person who can tell you more about something than you really care to know.
