Wei Zi was holding his fingers in a coma.

The following is my own understanding and personal opinion:

Sleeping is different from being in a coma. When you sleep, the nerves in your body rest, but when you wake up, you work. Just like when you go to work, nerves belong to consciously stopping to work. Coma, on the other hand, is not. Coma is a sudden interruption of nerve sensation and a sudden connection when you wake up. You may have seen the scene where the closed circuit is suddenly disconnected (forming an open circuit), (in the case of uninterrupted power supply) and then closed. If you don't understand, look at the picture in brackets (this scene means that when a circuit is powered on, it suddenly loses power, similar to your sudden coma. When you connect the circuit by hand, you close the circuit again, that is, turn the open circuit into a channel. Sometimes there is a discharge where you connect the circuit. It seems to be caused by excessive current for a period of time, which generally does not appear. Of course, no one will connect a circuit without interruption. It's too dangerous. I am just giving an example. ) and this sudden disconnection means that you have been ambushed (or otherwise, in short, you have lost consciousness and are in a coma). It can be understood as an open circuit of the body, but the body will automatically connect for you (connect all nerves to make you feel). At the first connection, (similar to the discharge imagination in brackets, there is of course current in the human body, but it is quite pitiful, as if there are 1 point around the heart? I forgot, I'm a scum with a poor memory. I have graduated for three years. This is my own understanding. Your answer upstairs is far-fetched. Why does that man want to eat? Because people are hungry? -.-|||
