Time always feels like it's passing by very quickly. Is this feeling caused by human physiological reasons? Yes, it was an illusion called the " Time Illusion ". Our brains sometimes trick us into thinking that we don't have enough time, as if time isn't as long as we think. This feeling may be caused by our attention being drawn to the task or situation at hand, or because we have a strong memory of the past. The illusion of time may also be related to our perception of the past and future. How we feel about the past and the future depends on our experiences and beliefs, and these experiences and beliefs often affect our perception of time. For example, if we feel that the future is full of hope, we may feel that time is not enough, and if we feel that the future is full of uncertainty, we may feel that time is long and boring. The illusion of time is a cognitive illusion related to our brain structure and neural activity.
