Wine, whiskey and many spirits. I had some 15 year old Heineken that had
sat in the basement. It had turned very dark, but it was a delight to drink.
Many woods develop color and character after decades. Many string
instruments improve vastly with old age.
Many building materials look better aged. Old brick has character.
Chiles and soups are often much better the second serving.
Many performers and people get better as they age. Experience and
knowledge.
Too many others for me to list as I feel like I'm getting old.

Beef gets better with age, assuming it is aged properly.
Beer, scotch, wine, fruit cakes, like xmas cakes.
