Hysterical strength allows someone to lift a car off their child

When the body responds to an acute crisis—say a family member trapped under a car—people can sometimes perform seemingly superhuman feats.

Why you have to airlift rhinos upside down

Conservationists in Namibia have found that airlifting rhinos upside down is actually better for their health than lying them down on stretchers.
