We're two bone marrow donors. One of us ended up running a marathon with his recipient & one of us is record-breakingly young - AMA!
I’m Sean, and back in 2012 I donated my stem cells to a father of two, Johnny Pearson. Three years later, he’s still alive – and we ran the London Marathon together last year! (He was quicker - https://www.youtube.com/watch?v=1kQuecUjA_E)
And I’m Ethan. Last year I donated my stem cells via the old-fashioned method (bone marrow extraction, general anaesthetic). I was 17, which makes me the youngest bone marrow donor in the UK, ever. http://www.bbc.co.uk/news/uk-england-nottinghamshire-29114638
We’ve also got Ann from Anthony Nolan (the UK’s biggest stem cell donor register www.anthonynolan.org) on hand to answer any questions about the charity’s work or the science if necessary.
Our individual comments will be tagged at the end like this -Sean or -Ethan.
Edit: We forgot to say we'll be here answering your questions from 3-5pm GMT today
Edited at 5pm GMT: Thanks so much to everyone for your questions! We won't be answering live now, but if any questions come in overnight we can answer them tomorrow morning.
