Be 90 and interested in living

There is one slightly old guy from US, who is amused to live his late years as complete as he can and also to share his experience with all in the Internet.
This is his blog and his AMA on Reddit.
Some notable points:
1. was in Marine Corps during WWII
2. got 3 college degrees via national program Servicemen's Readjustment Act of 1944 (G.I. Bill): BA - History, Latin and Athletics - to become a teacher and coach,
MA - Counseling Guidance - for school counseling,
PhD - Educational Administration - for various administration positions
3. "And I believe the social media as they/it are presently used are overrated and underrated. There is a time and place for everything, and I sometimes think they/it are like a new child's toy. Yet I think they hasonly begun to find their use as an instrument for furthering democracy and good government"
4. -What, in your opinion was the worst fashion trend?
-The zoot suit. We even had a great song about it in the 40's. But I also feel a BAD trend was the plainness of mens clothes most of my life...
5. -Thank you for your service ...
- ...Regarding "thanks for my service" I must add that my time in the service has been more than repaid to me by a caring, supported, NEEDED government that made it possible for me to use the GI Bill and a host of other benefits.
