They should have made them go through it for at least 4 hours though!!
I dunno...maybe make them walk around with pins stuck in their pelvic bone for a few days before the experiment. Then there's the back. They should club them over the lower back.
Yes, Netti, but we can imagine the pain of getting a kick in the balls. Men compare child birth to that (some) but imagine how they would like to be told 'your kick in the balls are now 3 minutes apart'
