I'm leaving a desk job I've had for 10 years (will be about 12 before I get going in NS). Before that I taught elementary school and was on my feet all day. I'm looking forward to moving again! Sometimes it's nice to sit all day, but it definitely takes a toll on your health.
Speaking of, I had to start walking regularly. I plan to start visiting the gym to lift some light weights and gains some strength back. I'm also in my 40s, and it's tougher to maintain my strength.
I also plan to stock up on ibuprofin.
