Travels with Darwin: On Sapolsky, and living in interesting times

Travels with Darwin: On Sapolsky, and living in interesting times: "The punchline is that olive baboons, like humans, exhibit maladaptive hormonal responses to social stress. Basically, these hormonal responses (glucocorticoids) release as part of a stereotypical flight or fight response to stress. This response ramps up your ability to flee if a lion is about to eat you, for example. But, as Sapolsky put it yesterday, if you're stressed because need to run away from a predator, your body sends energy to your thighs. Great. But if you're stressed because you're a baboon who's trying to form fragile alliances....your body sends energy to your thighs. If you're stressed because you're on a blind date....your body sends energy to your thighs. Not quite so helpful in these contexts. What's more, your body does this with hormones that can negatively impact your stress levels long term."
