As I get older I have:

… more fat and less hair. I don’t really care about the hair, but the fat is annoying.  Advantage youth.

… fewer unexpected mind-blowing really fun experiences, more moments where I am completely content with who I am and where I am.  Wash.

… less material desires.  Advantage aged.

… more patience.  Advantage aged.

… less stress and more peace.  Advantage aged.

All in all, older is better.
