At least I think it’s a joke….
“From the age of six I have had a mania for sketching the form of things. From about the age of fifty I produced a number of designs, yet of all I drew prior to the age of seventy- there is truly nothing of any great note. At the age of seventy-three, I finally came to understand somewhat the true quality of birds, animals, insects, fishes - the vital nature of grasses and trees. Therefore, at eighty I shall gradually have made progress, at ninety I shall have penetrated even further the deep meaning of things, at one hundred I shall have become truly marvellous, and at one hundred and ten, each dot, each line shall surely possess a life of its own. I only beg that gentlemen of sufficiently long life take care to note the truth of my words.” Hokusai.
