DeepSeaDan:... I think we all must accept the fact that on any given day, a set of uncontrolable personal physiological / emotional &/or psychological factors may combine with a specific exposure to create a problem - at times minor, at other times more serious. I think it is safe to say that our understanding of dcs remains limited at best, & it will likely be many more years before what is now often inexplicable will be understood. DSD
I don't think you could say it any better than this.
Our thoughts and prayers are with the diver and the diver's family.
We hope for a full and speedy recovery
