I've been away for a few days, down at The Island. Only skimmed this thread...
But, even Kelly Slater has had his own inner struggles, and inner demons. Admittedly, cleaner demons, compared to say Andy Iron's demons...
But Kelly did struggle with being nice to people, and got many peers off-side at a personal level, (felt he had to hate his opposition, in order to beat them)... Although most peers were continually gob-smacked at his abilities and achievements. He been able to make-up for that in the last few years though. He's also fully into nutrition and diet. Keeps his slowly aging body in top condition... Yes, he's a freak!!
