He is about 41 years old. At this age cricketers usually get involved in coaching or someone else gets involved in another profession.
But Mahendra Singh Dhoni is still playing Divya.
Also in competitive tournaments like IPL.
Still leading Chennai Super Kingsbay.
He said that he will play and lead next season as well.

This time IPL did not go very well for Chennai.
They finished the tournament at No. 9 with 6 points from 14 matches.
Chennai Super Kings lost to Rajasthan Royals by 5 wickets in their last match in the group stage yesterday.

Not playing in Chennai and not thanking the fans would be unfair. Mumbai is a place where I got a lot of love as a team and as an individual. But it is by no means a good thing for Chennai fans (announcing retirement in Mumbai).
