-7. It's ok. Here young dragon. Have a seat and allow me to elaborate. You see it's all simple. It's called the bed of nails theory. If you step on a single nail. It would hurt a lot because it's just one nail on one part of your foot causing an imbalance and in turn making the pain more prevalent. However a bed of nails is more balancing because no part of the nails stick up more than the rest. So because there is no imbalance the mails cancel each other out and makes the pain less prevalent if there is any pain at all. Science yo! *drops mic and walks out*
