No, you can't see the bones
When building the Hoover Dam, about two workers died every day from heat stroke. The tunnels they made could get up to 140 derees. They just tossed the bodies in the concrete when they were filling in the molds to complete the structure. Bodies of dead workers were also tossed in The Great Wall of China when it was built.
Looked like an animal
People who keep everything in and dont get angry or happy at some point in their life they are going to explode and go crazy and wild and usually end up hurting themselves.
