I´m 51 and also already grandma of two boys ;-)  I also was surpriesed how many people arround my age are mad in digital art too.  I think we have been the Woodstock-Generation, Hippies and Blue-Jeans Kids, so we haven´t really become oldfashioned in our minds. The real life has changed much against 1969, when we all had a great dream of peace and freedom, but with our art we can go back into our dreams - far away of the reality. Isn´t it? ;-)
