If a given behaviour is determined principally by the ready availability of certain combinations of neurotransmitters, with chemically redefined such concepts as freewill and responsibility, and we've removed a lot of the romance from falling in love.

Chronic stress is a factor in a high percentage of the illnesses that plague our society, and it can reduce the effectiveness of the neural systems that regulate learning and memory. Don't delay the onset of your personal exploration of the biological revolution that is already upon us, and the educational revolution that will assuredly follow. Become a leader and not a bystander.
