Hearing loss/deafness is one of the non-viable disabilities we have. The internationally recognised Sunflower symbol has been a great idea.

A badge or lanyard is worn by the person with the disability (with no indication as to what it might be). But it quickly alerts the more able, who know about it.

Many don't know about the Sunflower symbol (often seen at supermarket checkouts for example). It often means - 'I may be unable to hear you'. Or I'm autistic.

It looks well worth a go, doesn't it? I bought magnesium for something else recently and forgot why, so I have already got a full bottle of tablets.
