Does my bum look big in this?

Just a random picture I found. I'm doing a bit of CBRN training. There was point when I thought I was going to die. The battery in the internal fan ran out and I wasn't getting any air to my suit. I quickly started to feel faint and frantically tried to get the suit off but couldn't as my gloves were taped to the arms with duck tape. Everyone thought that I was larking about until I fell to the ground. When some one eventually spotted that I was in trouble I was able to get the hood off. Wow, what a rush of air. The tunnel vision soon went away and I was back to normal. That was scary!
