Hi everyone can you help me with this please thanks

Hi everyone, my name is Joe. I am currently doing a research project on Parkour & Freerunning. I am aiming to find out about it what it involves, how it started and what the differences between the two are. I was wondering if you would answer the following few questions please? It would really help a lot as I need to survey someone but I don’t know anyone, so I would really appreciate your help.

1. What got you into Parkour/Free Running?
2. Are you in a group/club of Parkour/Freerunner’s?
3. Where would you practice?
4. How often would you practice?
5. What are the dangers?
6. How did you learn the limits to your abilities? (such as jumping distance)
7. Is there many competitions for Parkour/Freerunning?
8. What are the basics to know about Parkour/Freerunning?
9. What is the Difference between Parkour and Freerunning?
10. Is there much confusion between the too different sports?
Many thanks, Joe.

1. Dunno. Really! The same thing that makes my ride a bike, drive a car or do whatever else I love to do.
2. Nope.
3. Anywhere, but finding some walls or stairs arranged in a "strange" way would be the best. It's not vital, though. Personnally I don't practice in the countryside often.
4. I'd love to train 3 or 4 times a week, but am always lacking time.
5. Read my signature. If you follow these simple rules, there aren't any dangers. Well, you have to be physically prepared, of course, but that goes on without saying.
6. It's natural. You don't learn such a thing, you feel it. Think about the animals: how do they know how far they can jump or how fast they can run? It's instinct; and we're trying our best to wake those instincts back up.
7. Well, there are Freerunning competitions, such as the Red Bull Art of Motion, but the pk community doesn't recognize them. Now later there has been a pk "competition" in the US, but from the looks of it it seemed more like a training with many traceurs and a stopwatch. Link to the video here.
8. Wikipedia is your friend , the article is pretty well written.
9. Same as 8. Pk = efficiency, FR = movement for pleasure.
10. Way TOO MUCH if you ask me. If you could do something about it, we'll sure be veeeery grateful. I'm serious.
