Some things you only find out about when you grow older. Take rheumatism, this is something I never even thought about until just a few years ago. Of course I had heard of it, but it was something for old people, very old. But now I see more and more people around me, all having about the same age as I do, suffering from some sort of rheumatism. Some more serious than others, but still. I really want to stay healthy for as long as possible, so lately I try to read as much as possible what can be done to at least minimise the damage.
