The world is your oyster
Anyone who retires from a long career where; structure, teamwork, leadership, technical savvi and discipline are prevalent - Military / First Responders / Law Enforcement etc. they are extremely desired and sort after by industry as a whole!
These skills and abilities are ones that you cannot teach except be being immersed in them for a long time.
Seriously, if anyone with this type of background was to approach a commercial organization for "looking for something to do" they will do everything in their power to cater to your needs and desires - short weeks / type of role / offer flexibility etc.
Best of Luck - Just remember you are wanted and needed for your second career, whatever that my be!
