in my spare time, i do it til the head turns purple and blue. i do it on the couch, the washer/dryer (in that order), the kitchen, the toilet, the patio, the roof, behind the TV, near the ashes of loved ones passed, driving past graves, in school, at graduation, in bars, in clubs, in strip clubs, church, restaurants, movie theaters, pools, at the track, on the bike, and so much more. yup. i sure do love holding my breath just to see how long i can go without breathing.
