Tony Stewart retiring?

Throughout these last few weeks I've been seeing a lot of articles asking if its time for Tony Stewart to retire. As a Smoke fan myself it troubles me whenever I see articles like that. Its not up to the media, the fans or Tony's friends when he retires. Its up to Tony & Tony himself. These last two years have been exceptionally rough on Stewart. Severely broken leg from a Sprint Car accident in 2013 & a fatal 2014 Sprint Car accident. Honestly I believe this year is sort of a recovery year for Stewart. No drama. No interruptions. What do y'all think?
