A thought: Most people don't even know how to set the refresh rate on their monitors.
They use their 4 gigaherz computers with default 65 Hz, their monitors literally 
are flashing and sometimes are foggy. Watching a foggy monitor is bad for the eyes. 

But good for them, they don't have to buy UV screens for their monitors for
eliminating flashing as well as harmful radiations that can cause blindness.
Instead technology comes with futuristic flat screens that are free from 
refresh rate problems.
