68 isn't too old to stop, Jon.

1. 68 isn't too old to stop doing things that *revolt* you.
2. 68 isn't too old to stop *feeling* revolted at what you do.
3. 68 isn't too old to stop having to *ready* yourself before #1 and #2.

 "Every now and then, when I think about what's involved 
  in eating meat, the thought *revolts* me.  The *feeling* never
  lasts, and at my next meal I'm always *ready* to tuck into
  a chunk of meat."

Happy birthday, old man.
