Jiu-Jitsu meets Theoretical Psychology. Brothers with blue belts. One, thirty-something and dad-to-be, wants to win the World Master Jiu-Jitsu Championship. The other, philosopher and doctor-to-be, wants to put in motion a cognitive science based behaviour change concept he has been developing called Ecobehavioural Design (EBD). Can they help each other and the listener to bring the best out of themselves whilst on the journey...? Contact @ecobehaviouraldesigns on Instagram
