Good point on 1. But simultaneously, we're telling parents not to eat peanuts (which is giving their kids peanut allergies), using dishwasers and lathering on purell constantly which damage our gut microobiome Immune systems are antifragile and need to be *properly* tested

Part of the difference too is that microbes historically evolved symbiotically with human beings. Because we lived in small tribes, killing their host was suicide. Modern day microbes are different. The population density has fueled the growth of bacterial superstrains

You probably should wash your hands after going to the gym, for example. But maybe not after going on a hike in nature

agree re immune system imo applies more broadly: brains and bodies are being subject to new and different environment this is stress, even if it's "not moving our body much" which sounds like "not stressful"

I suppose we could differentiate between healthy stress, which might be characterized as natural but in an unnaturally safe space (if such as possible), vs. unhealthy stress caused by modern conditions we are not adapted to. Choose your poison.

Athletics = safe spaces to fight in hunter-gatherer battles.
