As a 29 year old who played for 10 years before giving up at 18, I do miss playing cricket. I just had mixed feelings about going from 20/20 matches at u18 level to 50 overs.
I was never any good, but my (Limited) game suited 50 overs much better than 20/20, but I hated having to give up an entire day of my weekend, and definitely wouldn't want to commit to that these days.
