Anxiety evolved as a helpful emotion. It has prepared the warthog to escape
with its life... this time. If you're a warthog,
there's a pretty good chance you'll eventually be killed by a lion. But if you're a human, you're probably
worried about other things. We're smart enough to mobilize the exact same physiology as that warthog seeing the lion
at the other end of the field, and we do it worrying about
the 30-year mortgage we just signed on for
