Have you ever noticed that sometimes you find yourself looking at your phone screen just because? Or just maybe have noticed all the people that just hang out on the phone all the time? What if it was because the Hertz rate was making you feel attracted or pulled into looking at them all the time? A form of brainwashing. Yes it is very real.

2.4hz is interesting when you consider that 2.4ghz wifi is pretty much ubiquitous.Computer monotors and TV monitors can be made to emit weak low-frequency electromagnetic fields merely by pulsing the intensity of displayed images. Experiments have shown that the ½ Hz sensory resonance can be excited in this manner in a subject near the monitor. The 2.4 Hz sensory resonance can also be excited in this fashion. Hence, a TV monitor or computer monitor can be used to manipulate the nervous system of nearby people.
