LOL, If 20 is old, then I will be ancient since I will turn 27 in 2010. And since Harry is 17 in the last book, Dan will only be 3 years older than his character. It's not that big a deal. They are a year or two older than their characters now, and *gasp* they are going to continue to grow up! surprise surprise! It is exciting to turn the big 2-0 though. That's a fun birthday. But it is far from being "old."
