Here are some things I have done at various times in my life or do now:
Professional musician and music teacher - Artist, painting in oils, digital art and sculpting in clay - Feeding our avian visitors, (cardinals, brown thrashers, mockingbirds, sparrows, thrushes, chickadees, doves, woodpeckers, bluejays and hummingbirds, to name a few) - Caring for my dear pet badger (well, ok, so he's human .. mostly
)
Oh, and I did I say MINECRAFT! ? (I have been playing since beta 1.7)
You'll never be too old to have fun! Do the important things, but fit in the fun, too!
