unfortunately, i'm not sure what can be done. diet. yoga. chris marker filmed nine hours of india way back when, and i remember a 70 old yogi who looked as healthy as any human being on earth. as a consequence, i studied with a fine teacher and did my stretches for years. ironically, with my first back failure, i abandoned it, never to get back in the practice.

and i've added a series of drawings called the mayan underworld:
maybe playing with my smartphone will at least keep more than my hair and nails growing in the grave.
