I thought that video was supposed to show a successful attempt? "Easier" is a relative term. Don't remember saying anything about "easier". If I did, please show me. Maybe I should have said "more effective". Full suspension is more effective, I think. So is inert gas, but it costs money for equipment. I think CO is, too, but again, it costs money and needs to be done correctly.
Sorry, indeed, you didn't say the word easier.
I used the word easier as synonym for "a method with not a lot of failures". And indeed, you understood it, as you said, the the word is something "more effective".
I already tried inert gas, spent lot of money and failed : there was a leak in the bag, then I couldn't buy the proper pressure regulator (vol/min). I bought two of them, but the picture on the websites (two "professional" website) was misleading. And by the time I saw this, the return period had expired : the regulator were vol/pressure.
I quickly felt like I would run out of gas before I could really die, and the gas had filled my room, I felt dizzy.
Not a great, nor a peaceful experience.
Full suspension or hanging feels traumatizing ...
I'll look into it though.
