Nearly a thousand of you sent in questions for Josh Lewsey, our BBC Sport pundit inside the England camp.
Here are a selection of some of them, with more answers to come as each week of the RBS Six Nations progresses.
Q: What made you decide to plump to play for England when you could have played for Wales (Josh's mother is from Cwmllynfell in south Wales, and his father is half-Welsh)?
Hugh J Liskeard, Cornwall
I was born in England (Bromley), brought up in England, went to school in England, have played all my rugby in England and most of my friends are English. I am very proud of my Welsh heritage but when it comes to the World Cup I want England to win, and Wales to come second!
Q: Being in such an intense environment in the week before Test matches, how do you relax in and around the team hotel?
Tom, Perth
By the time you have finished training, you want to get back to your room and fall asleep. Relaxing is not a problem and we have some great beds here at Pennyhill Park, our base in Bagshot. Fortunately I don't live too far away either so if I want to go back home during the week I can.
Q: How fast can you run the 100m?
George Dean, Holland
I haven't been timed since I was 17 or 18, when I ran under 11 seconds, but I can't remember the exact time. These days it depends on whether it's in the morning or afternoon - at my age (29) I tend to be a bit slow to get going!
Q: You play full-back, wing and centre. What do you see as your best position and would you prefer to have a set one?
Marcus Jones, London
It is the most common question I am asked. Variation can be a good thing and sometimes in the back three I get very frustrated if I am not involved in the game and don't get my hands on the ball through no fault of my own. I just enjoy running with the ball and being involved, that is the most important thing. Hopefully the team play in a way where everybody gets their hands on the ball.
Q: How much can you bench press?
Rob, London
People get obsessive about bench pressing but to be honest I hardly do any upper body stuff nowadays. All the strength work is based around your legs, your bum, your 'core' muscles (abdominals, back, gluteals) - that is where the power comes from. I probably haven't done any bench work for two years.
Q: Why do players tape up their wrists and elbows so much. Is this for muscular support or to reduce the impact of cuts and collisions?
Nick Worthington, Shropshire
I do mine for a bit of support but there is also an insulating factor. You lose a lot of heat through your wrist, because your blood is so close to your skin. So there is an element of insulation and keeping your fingers warm on a cold day!
Q: Who is the hardest hitter (tackler) in the England squad?
Daniel, Banbury
Anyone can come up on the blind side and hit you hard at the right time. 'Noony' (Jamie Noon) seems to time his big hits quite well and Joe Worsley has put in a few in his time.
Q: Of all your team mates, who has the worst bad habits?
Beatrice, London
Joe Worsley - his personal hygiene is terrible!
Q: What do you eat for breakfast or lunch before a big game?
Helena , St Albans
I always have the same breakfast - a couple of pieces of granary toast with marmite, eggs and baked beans with black pepper. That is what I have had for years, and I can't really eat again before the match - I can't stomach it, I am too nervous. I just snack on a few bits and pieces.
Q: How important an indicator to England's World Cup hopes is the outcome of this Six Nations championship?
James Roberts, Thailand
It is not an important indicator but it is a litmus test of how far we have come, and how far we need to improve in terms of matching the benchmark the All Blacks have set, and superseding it. It takes a bit of time to make sure everyone understands their roles, but if we get that right we are a seriously dangerous team to be reckoned with.
