Kudos to these guys but I could not do this, just watching the video makes me anxious! I only have two phobias....one is Thalassophobia, fear of being dropped into the open ocean....and tiny caves!
Wen I watched this like half way through I started to feel suficashon and I had to turn it off for about and hour and I had to drink 5 bottles of water because i also felt unhidrated ❤❤
