Tendulkar, please be wise

Sachin Tendulkar is probably the finest one-day batsman ever.  Certainly the most profilic.  He's truly done it all, the most centuries, matches, Man of the Matches, there is not a team EVER at any stage which would not gladly take the little master to open for them.  But still stranded on 99 centuries, he's still got it as a test player but in one-dayers should he step aside?  He didn't need to play on after the World Cup victory, since he had then achieved it all and reached records in the one day game that will never be passed (Well he did get 200...). A player like Tendulkar should be able to call time on his career, but will he be able to do it at the right time?

Personally this writer thinks Sachin should become a Test Match only batsman and extend his glorious career there as long as he can
