3 . Any car accident is frightening, but an accident in which your vehicle is thrown into the water, with you trapped inside, is absolutely terrifying.     1    However, most deaths result from panic, without a plan or understanding what is happening to the car in the water. By adopting a brace(支撑) position, acting decisively and getting out fast, you can save yourself from a sinking vehicle.

Brace yourself for impact (撞击力). As soon as you're aware that you're going off the road and into a body of water, adopt a brace position. The impact could set off the airbag system in your vehicle, so you should place both hands on the steering wheel in the “ten and two” position.

Undo your seat belt.     2     Unfasten the children, starting with the oldest first. Forget the cell phone call. Your car isn’t going to wait for you to make the call.

    3     Leave the door alone at this stage and concentrate on the window. A car’s electrical system should work for up to three minutes in water, so try the method of opening it electronically first. Many people don’t think about the window as an escape option either because of panic or misinformation about doors and sinking.

Break the window. If you aren’t able to open the window, or it only opens halfway, you’ll need to break it with an object or your foot. It may feel counterintuitive (有悖常理的) to let water into the car.     4    

Escape when the car has equalized. If it has reached the dramatic stage where the car cabin has been filled with water and it has become balanced, you must move quickly and effectively to ensure your survival.     5     While there is still air in the car, take slow，deep breaths and focus on what you’re doing.

7 . April 4th was just another day on a Western Australia farm for Zac Mitchell, until it suddenly wasn’t. In an unexpected accident, the cattle worker was feeding the animals in his charge when one bull cleaned him up and kicked his hand up against the rail, resulting in the thumb on his right hand being cut off. “My thumb was still hanging on the rail... when I got up off the ground,” Zac Mitchell says.

His co-workers tried their best to preserve the thumb for reattachment, placing it on ice in a cooler, but two surgeries to put Mitchell’s thumb back in place failed. That’s when doctors came up with another suggestion: Remove one of his big toes to where his thumb used to be.

Mitchell’s lead surgeon, Sean Nicklin, understood the man’s dilemma at first, calling it a “bit of a crazy idea”. After all, Zac Mitchell did not want to be injured in another part of his body. But as the thumb is incredibly important function-wise, Mitchell eventually gave in. Nicklin explains that the big toe is surprisingly fit for a thumb switch: Nerves sync up (同步) nicely, and it looks more like a thumb, though a giant one, than any other alternative they may have come up with. He added that big toes aren’t as necessary for balance and walking as people believe. As far as the foot goes, occasional “fine balance” activities like surfing might be difficult, but most people without a big toe function fine in everyday tasks like walking and even competitive sports.

The eight-hour surgery went well, and Mitchell is expected to have a year or so of recovery in front of him before he heads back into the fields.
