Retire?  What's that?  Three kids to send to college.  That'll be what, about $1.2 million? No true Einstein's or sports stars in the bunch, either, so it wouldn't be on anyone else's dime.  LOL
Seriously, though, I plan on working as long as I will be able to.  I like having something to get up and do every day.  I enjoy get out and being with "people" (though being locked away in a lab may not exactly be "getting out"). I enjoy the income I have, and hope it will continue for quite some time.
