@Silverchild79,
I say, what difference does it make? They're all grown men - if they want to kill themselves in pursuit of records, so be it. Besides, nothing is more dangerous than driving a car around an oval track at 200 mph and no one seems to think they're nuts.
If Bonds or any of them croak at 45 or 50, they will die rich and happy with a legacy that can never be taken away, in my opinion.
