Mom worked insane hours to put dad through grad school in physics, then stopped once he got a job.
Dad worked at NASA for 35 years -- lots of stuff related to spectrum management and tracking stations. No clue where on the GS schedule he ended up, but it was pretty substantial for government work.
He retired in January. They bought a canal boat in Amsterdam a few months ago and will spend half of every year on it meandering toward Paris. Mom volunteers at the Smithsonian. They're busier (and having more fun) in retirement than they ever were with work/raising kids.
