Interesting! I graduated much later in life, don't put my DOB on resume and I've often been told that they expected me to be younger when they see me - now I get it!
One of the few perks of not finishing your degree until much later is the fact that you can put that date on your resume and people assume you're younger. It's expensive, though, considering how much and how fast college tuition has been shooting up in price the past 15 years.
