My first health 'issue' came at about 35. I was very fit field geologist leaping over mountains and the like. I had a blood test for something I can't remember (no MyHealthRecord then

) and it came back with very high iron levels in the blood - haemochromatosis. A genetic disorder (in those days poorly understood) where your body just accumulates iron and if left intreated the body starts shoving iron compounds into soft tissue, causing cirrhosis amongst other things.
No worries, fortunately they caught it early-ish and I just had to donate blood to remove the iron. Happily sailed on for another 30 years until another side effect started coming into play - arthritis (or greater effect of it). That's brought sometimes 2 tablets a day on flare-up and 1, possibly 2 operations, with associated strong painkillers.
I know there are others on here who have somewhat debilitating genetic disorders. So again, good luck
@Lynda2475 with continuing good health - with a bit more life experience you may gain some more empathy and understanding of others' conditions.
