Time machine

 My time machine isn´t as a common time machine (if there´re common). It doesn´t have a chair and you push a bottom to travel. It consists on some cables connected to your brain that measure your vital records to guarantee that you don´t pass through any problems during your trip. It also measures you physically and you go to the past as an illusion. This is that the place where you really are is on your times and the thing that travels to the past are your thoughts and a recreation of your body.
 This time machine is more secure than the common ones because it´s watched by some doctors and if they see any problem on the electrodes they disconnect you.

This is an example of the electrodes that you need.
