To be fair I got stressed from "A Pirate Looks at 40" when I was like...24.
Love that song though. Don't know if it would help your dad but whenever I get down about mortality I find comfort in this thought - Any small act of good can have a profound effect on the world long after you're gone, and knowing I might already have some unknown and silent legacy, selfishly, makes me feel better about leaving the world before accomplishing everything I'd hope to.
I really dig using "mook" as an insult, playfully or otherwise. It's somewhat normal in my tight circles but I get looks every time I'm in other groups when I drop a "what a mook"
