I was fortunate enough to meet Tendulkar back in 2002 when he played at Bradfield College when coming back from injury.
The guy is a class act in all aspects. We all know his cricket ability but the guy is very intelligent and incredibly approachable.
50,000 runs is an incredible feat and to him I am sure it is an incredible achievement but I think the pressure put on him by the BCCI, plus the weight of an entire nation, is something that he will always struggle to walk away from.
If I am completely honest... Superstars in cricket these days are few and far between, especially to the level of a Tendulkar, Warne, Walsh, Lara, Richards, Border etc... If he wants a few more games to break records - fair play. It's not his job to drop himself.
