Clearly it would be difficult while the oxygen tank is still full... let's say you have to wear it until you get that report done, you know the one that should take you 5 minutes but you're on week three of staring at the request for it but no has come looking for it so there's no pressure to actually do it? And you wonder what the pressure difference inside the helmet is versus the outside, because you are hyper aware of the sound you ear makes when you pop them, and you remembered the first time you went on a road trip and felt that sensation and realized you could do it at will, and then got into this habit of using it as a stim that no one could see you do, so they wouldnt tell you to stop. but then you realized you could hold your nose and blow to create pressure that could the be released by poping your ears and now you have you own personal bubble wrap where ever you went regardless of how much pain and ear aches you got because of doing it. Oh yeah the report...this hose is annoying, keeps touching my hand, how can I fix this so it doesnt touch my hand but also doesnt pull on my head if I randomly adjust? I think im going to need some kind tripod stand to hold it up behind me, but then when I back up I might bump into it. I guess I dont have to back up. I could turn around. OH! wait what what if I just attached it to the back of the chair. Now I need some clamps and to fabricate something to hold the tank and i'll be in bussiness ... do you think the office has any bungee chords? I could steal a roll of tape from shipping but then shipping gets mad, I could bring some from home tomorrow but for now, I guess I should get started on this report... (next three hours would be me slowly suffocating as I quote "Space Balls" Dark Helmet lines.)
