Thank you ladies.

I've met a whole heap of people now with an MS diagnosis, both on the Net and face to face, and among them are people from each MS group. Most of the ones I've met in person are either my own age, or younger.

Among them, most of the males have PPMS with varying disabilities, while the females with PPMS are quite debilitated and in the older age group, but although diagnosed in their 50's, their symptoms began years or even decades before diagnosis. The rest have RRMS or SPMS.

The reason I brought this up for discussion was (a) the subject interested me and (b) I thought I might like to reply to her claim, but then I could find nothing on the Net to either prove or negate her statement.

I personally think it's hogwash, but when replying to something posted by another person on the Internet (or anywhere for that matter), opinion doesn't count for much without the facts to back it up.
