kate & sazz - It's always been thought that it was only the mothers age that made a difference with downs and other genetic disorders and it's only since it's become more common for ladies to have younger men in their lives that they've even bothered to look at it. It certainly makes sense to me that it could make a difference. I find it weird that there's been very little research on it.

kate - I hope your MS improves soon. I've been really lucky - I haven't had any at all yet.
