Dhoni had, last year, said that he might have to give up a format to lead India's title defence in 2015 but such a decision would be made only at the end of 2013. Dhoni will be 33 by the time the World Cup starts in Australia and New Zealand.
The skipper said he is feeling a lot fitter and healthier than ever.
"I was really fortunate to see where I am right now with the amount of cricket that we are playing these days. As of now, it's looking good. The body is closely knit together. How it will be (in future), I don't know but so far so good," he said.
