I was reading a bit about neurasthenia (which - of course! - may or may not have any relationship to CFS), when I came across this factoid: it was considered typical that patients with neurasthenia looked 5-10 years younger than their actual age. This was striking because it's true for me, and also for my best friend since childhood, who also now has CFS (she first became ill at 18, I at 33). We both look markedly younger than our other friends. I never thought anything of it until now. Thought I'd just throw the question out: anybody else look strikingly younger than they are?
