I fell ill in 1988 when I was 35 years of age. However, I think that there were early signals from childhood that I may have missed: 1) During grade/elementary school I must have missed 40 days of school a year due to swollen glands and sore throats. My doctor never took my tonsils out though. 2) I had high energy in spurts, but no stamina. I could run faster than most kids, but would peter out pretty quickly. In high school I could not play soccer or basketball as my body just could not handle the energy requirements. Instead I played baseball/softball, golf, archery...etc. I was strong and athletic, but no stamina. Curious about what others may have experienced. Did you also have stamina issues or other early signs?
