I wonder if John would still be intensely into that whoel Macrobiotic philosophy. He was pretty dedicated to that whole whole-wheat, non-dairy, non-meat, etc. crap, wasn't he? But he did still smoke, though I know he was always quitting.
One thing I know...he seemed to be adament about taking good care of himself in those last years. He was all about watching what he ate and drank, and he had that book "Sugar Blues." I read that.
I actually think he looked good in his last years, but he was TOOOOOO skinny. He could have gained, like, 30 pounds.
