Marshall, congrats on your retirement day (today IIRC).
That’s a big move, I made it 12 years ago at age 55, loved my job but it’s still the best move I ever made from a quality of life, health and sanity standpoint. Be sure to quickly settle into a healthy routine with plenty of mental and physical stimulation. Set learning goals and vacation goals. Focus quality time on the family that your job may have been preventing you from doing and be supportive of your wife as she adjusts to your life changes.
And of course, you’re always welcome to hang at my house for bass fun and jamming.
