Nah, you get to retire and do what you want with your life now. Try pushing forty and still not knowing if you should build a snowman or go a sleep on a random Saturday night :)
I retired from the Navy after 20 years, but I still had to work, so I taught High School science for 20 years. Now is sleepy time for me, so I can get up a 0700 and do nothing for the day.
