The true professionals know when and how to bow out of the sport and don't hang around past their sell by date. I admire the top sports people who step away at their peak as they have achieved everything they can. No one wants to be remembered for not walking away and there are plenty who don't do this. If they didn't have a name behind them many would not be selected for the various teams they play in. I find that part sad as they are destroying a career of great memories.
