The following reared its ugly head from the period July 2020 to July 2021. All are chronic and have been symptomatic from: back: 1978, shoulder: 2000, knee: 1978. They all finally became chronic in this period..right after turning 60.
Nevertheless, I still lift 3-4 times a week, walk 4-5 times a week, swim 3-4 times a week…not that I’ll win any athletic awards. But I’ve really had to manage my activities.

Above: my spondylolisthesis at the L5-S1 (L5 is too far forward and my S1 (top of the tail bone) is tilted forward . I’ve had this since the mid 1970s but it finally became a chronic problem in July 2020 or so

See the top of my shoulder (acromiale bone)? That is supposed to be straight. The os segment never fused properly. This has caused me rotator cuff problems off and on, and it came back to haunt me in April 2021


Knees: that right knee has been operated on 4 times: 1978, 1979, 1984, 2010. (left only once in 1984). Well, the wear and tear finally caught up to me in July 2020. When I ran, I could feel the pain go down to the top of my shin bone.
Notices in the flexed position, the spacing is all but gone.
