i went to the PO and one stop shop with dh and dd2+3. dh and dd2 went to get a bottle of water, a man stocking shelves stopped dh and said 'is that one of those artificial hearts?' dh was gobsmacked to say the least lol. no-one outside of harefield has known what it is, we even had to explain how it worked to some of the nurses and docs here.
word is spreading....
