I worked next to nuclear researchers at Argonne National Laboratory, but left in 1969 (in order to move back to Ohio and family, I became a structural engineer--electric power transmission poles and then storage systems, not buildings or bridges!) I still have feelings for nuclear research and the nuclear power industry, but need to update my knowledge, because I don't know enough about current reactors and reprocessing of the fuel.
"Never continue in a job you don't enjoy. If you're happy in what you're doing, you'll like yourself, you'll have inner peace. And if you have that, along with physical health, you will have had more success than you could possibly have imagined." -- Johnny Carson
