Expires in 2019

I just received my renewed driver's license in the mail.  My state now does them via mail, which is great.  My new license does not expire until 2019.  This freaks me out.  I remember when I got the last one and how the expiration date of 2010 seemed so far away.  A will be 23 in 2019, already likely out of college.  The passage of time is terrifying.
