“Angela grabbed the side of the car with both hands and pulled up with all her strength. The AP account said she raised the car four inches; she doubts it was that much but believes it was enough to take the pressure off. She recalls nothing about the rescue, but the AP said two neighbors reinserted the jack and dragged the boy out. (Tony recovered OK.) Angela, then in her late 50s, guesses she kept the car propped up for five minutes. She describes herself as 5-foot-8, large-framed and strong, but figures she couldn’t have picked the car up under normal circumstances, attributing her feat to adrenaline.”
This seems basically impossible, but what is happened to Angela is that her body physically started to shut down all of her other bodily functions in order to use all of its energy and strength on one single thing, like lifting a 3,000 pound car. Things like digestion and immune response stopped working all together for those five minutes. But it was possible, which is amazing.
