CARS,
Bless you, this must be difficult. But onward, and upward. !!

You will get in the groove soon enought. Time to put up the
"GONE FISHING" sign.
I remember when my dad retired he had worked for
GENERAL DYNAMICS for 45 years at plant 19 here is San Diego. He was a bit lost for the first 6 months. Took him about a year to relax.
You know you can alway do
VOLUNTEER work, I'm sure a man with your education,and skills would be sought after. Volunteer work is very rewarding.
BRAVO !! YOU WORKED YOUR BUTT OFF ALL YOUR LIFE.. NOW IT'S TIME TO LET THEM YOUNG PEOPLE TRY AND MAKE IT 44 YEARS..!!
