Ever wonder why this seems to be the case. It is because you can only comprehend eternity by associating it with the longest amount of time you yourself have experienced, which of course is your entire life. From the time you became conscious (birth) to the present moment, which is always moving forward in time. So therefore your perception of eternity is constantly expanding while the time frame of a year is not. So a year, to a 100 year old man, is 1% of eternity, while a year, to 1 5 year old is 20% of eternity.
