The premise is completely wrong. If you are young, you don't know what percentage of your life one year is. More likely explanation is the compression of memories: if you experience things that are similar to things you have experienced before, they won't use up as much memory. Think about your daily commute to work: can you remember every single day you commuted? Or did all the commutes blur into one?
