Quote ="Cronus" I bet hundreds of cricketers have been within millimetres of something similar.'"
To be fair, I think 99% of sportsmen play their particular sport for the thrill of that danger, whether it be cricket, either rugby codes, skiing, car or bike racing, horse racing, etc.
I'm in my mid 40's and still play cricket, keeping wicket and batting mid order, and over the years have had my share of bruises and breaks. However, I still get a buzz from being challenged by some young lad hurling the ball at me - Its almost unexplainable why I want to do it, but I imagine most sportsmen feel the same.
Sadly, Philip Hughes probably got that same buzz too and tragically paid the ultimate price for it, but to take that element of danger from the game, and with it the buzz, would end up diluting the sport to a level where the game wouldn't be worth watching or playing anymore.
