Gulp... thanks for your service!! Would you believe that until I was in my 30s, I thought a grand jury was comprised only of retirees because of the amount of time it took?? (In my defense, the only knowledge I had was that my only former-grand-juror friend was a senior citizen). Once a few more years had passed, and I had been to individual service a couple times, I finally put this together with "a jury of your peers"
and figured out that yes, some times people got stuck on grand juries when they were still employed.
