Muscle bound, interesting.
Can you tell me how to interpret this? I don't know if I get it right.

My early experience with weights were also rather special (and early) - still for my time. It was all psychological for me, I was 12y lying in an chilly isolated hospital room where nobody was allowed except for the doctors for a period of 4 weeks while receving stemcell transplantation.

One day they asked me if they could bring me something, and my inner voice told me to ask for dumbbells (the old fashioned ketler's with screwed weights). It was somewhat the only items I could receive sterile too. The feeling of the cold metal on my hands, and the idea only that I could lift those weights (app 6 kg) gave me a mental boost (today I still think it contributed to my healing process).
This morning (25 years later) I still got that same sensation when I did my incline benches.

What I want to say is, there's serious positive benefits attached to lifting, and especially continue lifting during your lifespan.

I was early on the computer scene, since I was assembling my own PC's early 2000s. Due to that, I was very early to download and absorb movies from the golden era.

This is as far as my imagination reaches towards your 50s years. Impressed by how early and long ago you were awake. Much respect for this.
