I saw an article "Premature Aging Caused by Some HIV Drugs, Study Shows" where they say the hiv drugs damage mitochondrion. As one of the theories for CFS/ME is mitochondrion dysfunction, I thought it would be interesting to discuss if the symptom of aging is present among CFS/ME patients. I personally look younger (maybe mainly because I am underweight), but it seems my body is regenerating extremely slowly - last time I got sunburn, the skin started to peel off after two weeks, instead of two days. Also there is a test measuring end glycolysis proteins, which can be mapped to the age, and according to the test I was older by 5 years. Such results can be received with a prolonged illness or diabetes, I was told. Did you notice any abnormal aging?
