“Age has no reality except in the physical world. The essence of a human being is resistant to the passage of time. Our inner lives are eternal, which is to say that our spirits remain as youthful and vigorous as when we were in full bloom.” ― Gabriel Garcia Marquez , Love in the Time of Cholera.
Within western cultures aging is stereotypically portrayed as something bad, to be fought against. Artists however seem able to live beyond these stereotypes. Art is one career you can get better at even into old age.
