Better With Time

Do all things improve with age? I have heard that before but I don't know who said it and why. I also heard it said that all things get better with time, is that really true? I just wonder sometimes. Maybe it is just our perspective of things that change or we think about them in a different way. If that is so, than it doesn't really take time per se, but rather it takes our mind or wisdom instead. I am learning something new everyday, and that is what I believe gives me the wisdom that I need.
