Has anyone here who does breath play seen the movie Last Breath?

It is out in theatres on the big screen. True story of a deep sea diver who got himself knocked out by oxygen deprivation and who was without oxy for 29 minutes and brought back to life.

There is probably a "Do not try this at home," somewhere.

Oh, the doctors think that the deep sea or the cold was partly responsible for his being brought back to life successfully, after 29 minutes, without physical or mental injury!
