I'm turning 30 this year, and a lot of things have happened in the past five years to make me realize how different I am from when I was 25. How you feel about your age has a lot more to do with your experiences than the sequence of the Earth taking a spin around the sun, and video games help keep me grounded so I don't end up being TOO old n' crotchety anyway.
Now get off the lawn you lousy kids!!!
