I'm ancient. When I started working, the company had a pension that would have allowed me to retire at 55 with 85% of my final salary. Many years ago, they got rid of the pension program (I'll still get something, but far, far less).

When I turned 55, I was initially pissed off about that. Then I realized that I likely still had 30 years or more to live. That's a really long time, and it hadn't really occurred to me before.
