He must have been troubled by demons most of his life : the pursuit for perfection.
Indeed. My wife met him quite regularly over the last few years, she's in the medical research business and he was often in her clinic. He'd led a challenging life that's for sure, but she tells me that he was very decent to talk to as he had his fag breaks outside. I think life dealt him a pretty poor set of cards to start with, and he'd probably be the first to admit that he played them badly too. It's a real shame to see him go that young, quite a character.
PS: On threads like this, it reminds me how nice it would be to have a "dislike" button. A man's died relatively young, and some find it appropriate to dish out the pithy comments.
If you have nothing nice to say, it's still an option to say nothing.
