I used my altitude generator 11 years ago. I still have it. I don't have the tent, but you can just make one. I can't sleep in it, but l am thinking of using it while watching tv or other stuff. I got married a year ago and my wife won't sleep in a tent. I am thinking of pulling it out and using it 5-8 hours a day as l watch tv or do other stuff like that. Will this take me to the next level. 10 years ago l noticed a lot of benefits, but l am not sure if it's because of the hard workouts l was doing then and the benefits l thought l got from the tent were in my mind.
