I (hubby) retired first. Although high paying, my job was inherently stressful and physically dangerous (two potentially fatal close calls). Once we reached a certain "number" I had no hesistation on pulling the plug - without the meat-grinder job, these past two months have been the best of my adult life. My wife loves her job, and unlike myself, is unsure how she would fill in the hours of the day without it - though I think she may be starting to get it, watching my metamorphasis up close.
Sometimes I wish she would join me in ER , then we would be free to spend months at time at our condo in the Baja - but then again, her choice to continue working will pad the "stache" some more, and allow our lifestyle to be potentially higher in retirement once she joins me. She thinks she wants to work another 5 years - but is also threatening 10... I am lobbying for 3. :)
