I'm still planning my return to work! I became a teacher at a terrible time, had a baby and will be home for at least the next 4 years with her and at least one more kid if things go as planned. So I'll be returning to the workforce late in life (late 30s, posslibly 40). My husband has us set up well, but I enjoy working and loved teaching and will work for some time; I'm thinking until I'm in my 60s.
I'd like to retire at age 66. I was laid off two years ago at age 55, and I was NOT ready to retire. I'm back to work now, and very happy about that. I really enjoy my job and having a place to go to when I get up in the morning.
