Interesting to note this from the 'Press' section;

EQUILIBRIUM
Goddard, who is currently working on an anti-stress programme at U.S. investment bank Lehman Brothers, said the symptoms of stress --such as a faster heart-rate and increased blood supply to the brain -- once had a more positive function.
    "It was great when we had to fight bears."
But today people find it hard to de-stress and return the body to equilibrium, she said.
    "We can forget how to switch off the on switch."
Her sessions at Lehman Brothers highlight stress-relieving strategies including exercise, as well as adopting a different perspective on the work environment.
    "I get people to be silent for five minutes and just look out of the window. That helps to calm people down and get the heart in
equilibrium."
