I have to admit that I have mixed feelings about that. I think it's more than just "selling products" - at least I hope it is. I think it's important that people of various abilities be made visible in media for the purpose of social inclusion - not hidden away from sight like they are in countries such as France and Japan. Do an Internet search, and you will see that France banned a beautiful advert for World Down Syndrome Day.
No I haven't, but most major illnesses have their own ' Day '. I hope that it is a day where they celebrate the accomplishments and achievements of these individuals who contribute to society in so many different ways
