kk isn't really just some random old person, he was Wired for all intents and purposes for a long time, he is an astounding and empathetic travel photographer and is one of Stewart Brand's best friends. I realize you were speaking generally but I hope we can all make an exception for this one random old person. Do yourself a favor and turn the pages of Asia Grace. Ageism is a hell of a drug.

sneaky edit: if I could get life advice from any random old person, he would definitely be on my short list. The guy knows how to live.
