I “retired” at 44 years old from a 25-year career as an IT professional. Originally working six years in academia followed by 18 years in the corporate world. My wife was able to leave her professional career a few years before I FIREd.
You may be wondering, if this was a smart decision. That’s a valid question—I think about it myself, quite often. Usually, while enjoying my day thinking “this is too nice to be real life!”
