The body adapts, but across evolutionary history the rate of
adaptation has likely been set by how nonstationary environments
tend to be. If you adapt to ease too quickly you become vulnerable
to sudden threats, while slow adaptation to ease might miss out some
fitness opportunities (stress and reproduction tend to be
anticorrelated) but likely less - not having as many offspring as
would have been possible is usually better than being dead. So I
would expect a bias towards rather slow adaptation. <br>

Anders, the biggest adrenaline surge I have had in the six
years since retirement is last year when you and I were
attempting to drive in San Francisco. {8-] That gave the
old adrenal system a good workout. {8^D</span></p>

Hahaha! Yeah, that was some trip. I felt bad for you. Maybe next
time we should try a slightly more calming environment (or not, to
keep the adrenal glands working). <br>
