A normal male has a blood count of around 140, I've never been 100. That gives you an idea of how serious this was.
How do I take a step? How do I lift my foot off the ground, move it through the air a little bit and then bring it down? I had to teach myself to walk again.
I always say to people that you have never seen the best of me, and that's what I mean - I've never been fully fit.
I am very excited to be here in Wales and look forward to putting on the Cardiff Blues shirt.
I know in my heart I'll be playing again - watch this space.
I thought about dying whenever I got bad news about other people.
I was diagnosed with the illness right before the 1995 World Cup.
I was on dialysis for 18 months before the transplant, so it was important I tried to look ahead to days like my comeback this Saturday. You need those big goals to drive you on.
I was only operating at about 80% of my capacity.
I was this guy who'd been racing around down there, on that field in 1999, running straight over people, scoring tries, winning games, having fun. And I ended up so sick I couldn't even run past a little baby.
It was like falling off a building and suddenly, bang, you hit the bottom. The first time it happened was on an ordinary day at home. I was taking down some curtains. I took one step, turned around, took another step and then I fell and hit my head hard on the rowing machine.
It's a really exciting time to be involved in Welsh rugby.
It's been a long road back to health and fitness for me. I am just glad to have been given the opportunity to do what I love most.
The biggest thing for me is just to get out on that field. Just to do that will be incredible.
Towards the end of 2003 it was hard to get through training - and the darkest point was when a doctor told me there was a possibility I could end up in a wheelchair.
When I was playing I felt tired all the time. My recovery period was a lot longer than the other players. They'd be ok after an hour - I'd have to stay in bed till the next session.
Jonah turned down a multi-million dollar offer to play American football.
Jonah is a giant New Zealand rugby player regarded as one of the world's best players ever. Bizarrely, Jonah plays as a winger - a position usually occupied by the lightest and smallest players. On his best form, it can take 4 or more players to bring Jonah down.
He was offered the role of the villain Gabor in the James Bond movie The World Is Not Enough (1999), however, he declined in order to concentrate fully on his rugby career. The role was then given to former Gladiator John Seru (a.k.a. 'Vulcan').
Jonah has a wax likeness of himself at Madame Tussauds in London.
Has the number 11 - which is his famous playing number - tattooed on his muscular chest.
Has his own Playstation game - "Jonah Lomu's Rugby"
He was awarded the M.N.Z.M. (Member of the Order of New Zealand) in the 2007 Queen's Birthday Honors List for his services to Rugby in Auckland, New Zealand.
