What is core shift?

I don't know, seen the last month job's report ? NO NEW JOB'S were created--in fact likely next month they be telling us the USA lost the number of jobs.

Job's are hard to find, let alone 90's ones. Not saying you couldn't find a job--no way with your background you be hired for sure--but for how much $$ its hard to say.

Bet you could handle Texas heatwave, lol. I believe Iraq is 10--20 degrees hotter than any place in Texas during the summer.
