@chayro +1. Essential to stay engaged. As Clint said, don't let the old man in. I find as I get older that simple DIY projects I could once do in my sleep somehow involve an injury much more often these days.
Like you, I've been in various forms of the law (and gov't) business and I've retired a couple of times. Most recently, I negotiated myself into working for no pay. As you suggest, that's not a great match for this hobby. Not a lot of pro bono in the audio dealer community.
