What do you think gets better with age?

I think life experience gets better with age, you know when we are still in our youthful stage, life may be all the party, the bottles, the break rules and all that the list is a bit long as you may know. I know experience may not be the best teacher as to be the best but at least with experience one can have a little bit of gist on a particular subject or field. I believe with time and age one can be able to give a thoughtful gist on what life is about.
