I know where you're coming from. It is one aspect of ageing, in that the reproductive age is coming to a close, but that doesn't mean the rest of the body will be ageing at that time. However I do think oestrogen keeps us healthy and makes other problems somewhat less likely. People have different views though. I've chosen HRT for this reason and I've noticed huge improvement in so many things, subtle things, that I personally feel that lack of oestrogen was ageing me in other ways and now I've arrested that with the HRT, and I really do feel I've arrested and reversed what was happening in my body. Joint pain virtually gone, some energy back, etc. But I have a friend who's felt no effects whatsover and is further along in the peri menopause than me.
I think science is beginning to understand the many causes of ageing in people now anyway, and anything it comes up with to delay that I will want to try. Not because of wanting to live forever but because a large part of ageing is just health problems, it would be better if we could all live out our lifespan without all those problems.
