Is MS Dhoni the oldest man to captain in all T20 matches?
And has anyone gone in at every batting position in the IPL?

Sunil Narine has worked his way up from No. 11 to opener in his IPL career, batting at every single position in between • BCCI
There's only one man who fits the bill here: the West Indian spinner Sunil Narine started as a tailender with the bat - he had only two innings in 15 matches in his first IPL, in 2012. He batted in three innings at No. 11, then started to move up the order.
The match you're talking about was a Women's World Cup qualifier against Thailand in Lahore last week: Bangladesh's legspinner Fahima Khatun took 5 for 21, while offspinner Jannatul Ferdus had the eye-catching figures of 5-3-7-5 as Thailand slid from 65 for 3 to 93 all out.
The Chennai Super Kings captain Mahendra Singh Dhoni is due to celebrate his 44th birthday on July 7. He's actually been the oldest IPL captain for a couple of years already: the previous record was held by Adam Gilchrist, who was 41 when he captained Kings XI Punjab for the last time, in Dharamsala in 2013. Gilchrist celebrated his impending retirement by bowling the last over of the innings - he was fairly safe, as Mumbai Indians needed 51 to win with the last pair at the crease - and took a wicket with the only ball he ever bowled in a senior T20 game.
I smell a sports-quiz question here! The Cheltenham Gold Cup, one of Britain's premier National Hunt (jumps) horse races, was won in 1991 by Garrison Savannah, trained by Jenny Pitman and ridden by her son Mark. The same year, the horse finished second in the Grand National at Aintree, just failing to pull off a double achieved only by Golden Miller in 1934.
You've got it in one: the South African batter David Miller has so far appeared in 308 white-ball internationals (170 ODIs and 138 T20s) without ever playing in a Test match. Kieron Pollard, the West Indian, played 234 white-ball games (123 ODIs and 101 T20s), while Scotland's Richie Berrington has so far appeared in 230 (123 ODIs and 97 T20s; Scotland haven't yet played a Test). Another current player, the Australian legspinner Adam Zampa, comes next with 216 (111 ODIs and 95 T20s).
