Breathing vapor of boiling urine increases lung power
"... Michael M. was concerned about the smoke that he was breathing daily and the effects it could have on his health. He heard a radio interview I gave in 1992 and attended one of my lectures. To test his endurance, he would time how long he could hold his breath, which was usually about a minute.
To clear his lungs he decided to breathe the vapors of boiling urine five to ten minutes every day after work. Four days later, he developed a severe "healing crisis" that forced him to stay home three days. Two weeks later, he started breathing vapors again, but this time he had no healing crisis.
Uropathy had increased his oxygen absorbing capacity so much that he held his head under water for more than three minutes to show his coworkers what urine had done for him ..."

To facilitate breathing the urine vapor, roll a few sheets of kitchen towels and position one end to the rising steam, above the lid of the pot. Most pots have an opening hole for the steam to escape. Take care not to be scalded by the hot steam.
This application of urine therapy may help asthma sufferers and people with lung problems.
