Not bad, thanks ummmm. I still get short of breath sometimes, which I put down to being anaemic due to the amount of blood I lost (4 litres, they said and you only have 5 to start with). Other than that the odd medic I've seen has been amazed at my progress so I think I was a bit lucky.
Incidentally, I had no prior symptoms that anything was amiss but the NHS are rolling out an ultrasound scan programme for over 65s to try to detect the problem in good time. It's exactly the same as the pre-natal scan and you won't be surprised to hear that I'm recommending all my friends to have one.
