Apropo of nothing.... hypoxia / anoxia is a good way to go... having done several decompression runs in the RAF chambers I can say fron experience that it is not unpleasant... you don't gasp for breath as in the movies, you are breathing air, it just doesn't have enough oxygen in it to maintain conciousness... you just gently drift away.... (until the doctor in attendance puts your oxygen mask back on for you that is)... should I ever consider ending it all that is the way I would want to go for sure.... not that I am I hasten to add
