Even though it's a shortened format of the game, Twenty20 allows people with different skills to play in a team and play their specific roles. Obviously there's not too much time to waste balls, but if you look at guys who play well in the top six, they have a fairly decent amount of good cricketing ability.
I find this mortifying to admit, but I have one of those balls that helps my posture. They're hard to sit on, so it stops me from sitting too long... I also wear a pair of 3M(TM) PELTOR(TM) Optime(TM) II Ear Muffs. They're the same ones that people wear on the tarmac among the planes - noise blockers.
