David Johnson, I agree that the breathing techniques will not help starving people as much as it will help the stressed out techies in Bangalore and businessmen in Bombay. From what I read Ravi Shankar is also teaching people regarding harvesting rain water which is more helpful to a droght stiken farmer rather than breathing techniques. Hopefully Ravi Shankar spend 10 hours on rain water harvesting techinque and 5 minutes in breathing exercise and not vice versa!
