Hey Chaplain!
Sorry to read of your retirement but you know more about yourself than the rest of us do. I'm retired also but I also suffer from COPD even though I've never smoked a cigarette in my life. I'm basically house-bound and don't get out much. I try to find ways to be active but am limited due to the oxygen I have to have 24/7. So I have become somewhat sedentary in my old age, I'm getting close to 80 years of age.
Look around your house, you're sure to find omething to do. Write a book, memoirs would be nice. I visit facebook often.
Lots of luck on your retirement. Hope to see you on this forum.
God bless.
