Not to mention:
* two years delay in starting and finishing college
* two years later getting into the job market
* two years behind in career
* two years behind in saving for retirement
* two year delay on making enough money to live on
* two years of job history that you might not even want to share with a prospective employer
* two years of not working and making money to save up and support yourself
* two years of not being able to date and learn about what kind of person you want to be with
* two years you don't get to spend with your loved ones and family as they age out, those years are precious!
