John, what is your opinion / answer to these questions that I asked?
Also, one of the major reasons that more American wrestlers are dying compared to Japanese wrestlers would have to stem from excessive non-pain killer / muscle relaxer usage ala cocaine, heroin, speed, meth, probably as well as the extremely over the top use of steroids. Now, I fully know that certain Japanese wrestlers use steroids, but they are nowhere near the level of consumption that the American wrestlers use. Also, considering the massive amounts of drugs, alcohol, and groupie sex, it's rather surprising that guys like Jake Roberts, Raven, and Ric Flair aren't dead.
I've noticed what you've mentioned about Misawa, he's always shaking something off, rotating his head / holding his neck, or shaking out his legs. I'm fairly surprised that Misawa, and especially Kobashi aren't wheelchair bound yet.
I heard that Misawa received a recent concussion against Morishima, yet continued in the match, and somewhat carried Morishima to a passable match. It's crazy though, concussions are nothing to mess around with, I've suffered through a few in my lifetime, and it's no laughing matter. I would how many Misawa's had in his career? Probably over ten, fifteen...?
