believe it or not, our perception in time could actually change. Our eyes take in information at 30 frames per second. In certain situations, the number of frames per second could actually go up, which means more information processed within the same amount of time. People around us wont notice the difference, but what about ourselves? As the fps boosted guy, you will perceive time slower through your eyes, but no scientific evidence showing your body will change accordingly (slowing down relatively to surroundings), but you can trick your body to slow down aging by reducing metabolic rate through certain activities.
