Emotional Exhaustion?

So, Shaun Tait decides to quit cricket "indefinitely" citing "physical and emotional" exhaustion as his reasons for doing so. Emotional exhaustion?

What does that even mean? He's really exhausted after all the emotions he's expended while playing cricket? Is frustration an emotion?

Sounds to me like the guy couldn't get a regular gig for the longest time, mostly due to injury and once he got his chance he stuffed it up and now he's packed up his toys and decided to go home.

Boo hoo I say, there's a million other guys waiting to take his spot. If he can't hack it, go pack shelves at Coles and let people like Doug Bollinger step up instead.

Good riddance.
