I am so, so scarred I'll become a conscious vegetable.

Really. I plan ot make an exit bag but... It doesn't seems reliable to me to be honest, Im worried that It won't be sealed enough and I'll just end up as a vegetable due to insufficient oxygen to the brain, but enough not to pass away.

Is it really legit, even wit no professional mask i.e. scuba? Even if it won't be sealed enough, and there will be let's say... 6-8% oxygen? What then? Is there a concentration that won't let you pass away but permanently damage brain?

The time when I may be found is not a concern. I'm able to be alone the whole day.

To me it seems more reliable than partial hanging, having an elastic band around the neck should keep the bag steady and prevent oxygen from entering. Also, putting the tube exit on the top of the bag should create a cushion of nitrogen that prevents oxygen from rising (nitrogen is lighter than air). It would be my main go-to method I think.
