but this is something that is fairly commonplace knowledge that everyone knows about.
I doubt that.
I would imagine there are a lot of people, particularly on this forum, who aren't all that aware of MS.
And if they are, I'm sure there are plenty who only know it exists, but don't know what causes it, what the effects of it are, how it's cared for and more.
Promoting awareness of medical conditions is a good thing.
It's not just about raising money for charities for research/care, although that is a part of it.
It's raising awareness for the symptoms of diseases, so that people can identify them and get them diagnosed. It's to prevent the spread of misinformation, which can prove harmful or sometimes fatal depending on the condition at hand.
And it's also a means of gathering support, financial included, but also emotional, for those suffering and their friends and families who also struggle with caring for someone with the disease.
